  • Linux Mint Maya Freezes

    - by timuçin
    Linux Mint freezes after a couple of seconds the desktop loads, in a way that I have to shut the power in order to reboot; the mouse doesn't move, ctrl+alt+f1 doesn't do anything and I think even the hard disk stops. This doesn't happen every start but when it does happen, I have to start recovery mode and run the option "dpkg", the description is "repair broken packages" or something like that. If I don't do that and start the system normally the samething happens again. I have some clues that might help: The first time I installed Mint I had to install my wireless driver manualy. The system didn't freeze before this but since I installed the driver immediately after the Mint installation that might just easily be a coincidence. Even so after I discovered the dpkg trick, for the first couple of times I did it, I found my wireless driver uninstalled and I had to reinstall it. The thing is I can't be sure that the problem is my wireless driver because the relation is not direct enough. Still letting you know what my wireless apapter might help: Realtek L 8723 The next thing I am going to do is to wait until it happens again and post the system log here.

  • 12.10 visual performance using nvidia driver

    - by user100485
    My fresh ubuntu 12.10 install is slow, not something extreme but dragging windows, switching workspaces and things like that are just slow and look horrible. it feels like the fps is dropping in a game. Doing some photoshop work in windows was even a relief! This effect gets worse if I connect my external monitor. My system is an intel pentium dual core T4500 with 4gb memory and a GeForce 8200M G/integrated/SSE2 graphics chip. Nothing fancy but should be able to run ok. My "experience" in ubuntu is set to standard. (MSI cr500 laptop) I've installed the nvidia drivers, tried current and experimental and the experimental drivers seem to perform a bit better but overall bad anyway. I set the mode to adaptive in the nvidia-settings tool and it goes to maximum setting directly and doesn't come back. Using htop I found out that compiz or the X server always use a few percent of my cpu, more than I think it should and the time consumed is 5:18 for compiz, 4:33 for /usr/bin/X and 2:41 for google chrome(about 30 tabs open so not too strange I think.) What can I do to increase the visual performance cause this makes me not want to use ubuntu in public!

  • Ubuntu 12.04 - Brightness controls not working

    - by Juan Manuel Zolezzi Volpi
    Controls from "Brightness and Lock" were not working so I've tried a solution that involved changing grub, which I'm detailing below: # If you change this file, run 'update-grub' afterwards to update # /boot/grub/grub.cfg. # For full documentation of the options in this file, see: # info -f grub -n 'Simple configuration' GRUB_DEFAULT=0 #GRUB_HIDDEN_TIMEOUT=0 GRUB_HIDDEN_TIMEOUT_QUIET=true GRUB_TIMEOUT=10 GRUB_DISTRIBUTOR=`lsb_release -i -s 2> /dev/null || echo Debian` GRUB_CMDLINE_LINUX="quiet splash acpi_backlight=vendor" # Uncomment to enable BadRAM filtering, modify to suit your needs # This works with Linux (no patch required) and with any kernel that obtains # the memory map information from GRUB (GNU Mach, kernel of FreeBSD ...) #GRUB_BADRAM="0x01234567,0xfefefefe,0x89abcdef,0xefefefef" # Uncomment to disable graphical terminal (grub-pc only) #GRUB_TERMINAL=console # The resolution used on graphical terminal # note that you can use only modes which your graphic card supports via VBE # you can see them in real GRUB with the command `vbeinfo' #GRUB_GFXMODE=640x480 # Uncomment if you don't want GRUB to pass "root=UUID=xxx" parameter to Linux #GRUB_DISABLE_LINUX_UUID=true # Uncomment to disable generation of recovery mode menu entries #GRUB_DISABLE_RECOVERY="true" # Uncomment to get a beep at grub start #GRUB_INIT_TUNE="480 440 1" After doing this, the brightness control dissapeared like you can see at http://screencloud.net/img/screenshots/6b90d56604b70cc749a632d0bc005a20.png Any ideas? Would love to be able to configure Brightness or even use apps like F.lux to regulate it automatically. Edit: I've modified the following line to GRUB_CMDLINE_LINUX_DEFAULT="quiet splash acpi_osi=" and now the brightness controls are back, but whatever I change the brightness remains the same. Just in case I'm using Intel H77

  • Graphic Card Installation Failure (NV 9600M GT)

    - by Georg
    I wanted to switch from 7 to Ubuntu. Now, the first thing that holds me back is the installation of the driver for my Nvidia 9600M GT. Ubuntu recommends me 4 drivers from the "Additional Driver" Section. Now, whatever driver I install, there are four things happening RANDOMLY after rebooting: The pc freezes before seeing bootup splash The pc freezes while seeing bootup splash image (ubuntu logo with the 5 dots) The pc gets into login screen and freezes instantly (Thought the unity-bar is transparent now) The pc freezes right after beeing able to login. (While this is happening the unity-bar changes from transparent to ugly-flat-style) I also tried to install the official Nvidia .run file but after exiting the X-Server, it says the driver is not compatible with the kernel and exits installation. Can somebody help me? I really wanna get rid of Windows :( But Ubuntu drives me perfectly insane. Please answer as noobish as possible. I'm an expert Windows user, but Linux is absolutely new to me. My Specs: Ubuntu 11.10 installed from USB Stick (like 100 times now :/ because I dont know how to remove the driver in recovery mode) 9600M GT 4GB Ram Intel Centrino 2 Dual Core 2.26GHz Win 7 and Ubuntu running along side. Thank you in advance, regards.

  • Won't boot after installing Ubuntu 12.04 sucessfully

    - by Matt
    I installed 12.04 successfully and rebooted (I took out my installation CD), and selected the newly installed Linux partition to boot from rEFIt. Then it just comes up with this error message: Error loading operating system which could not be more vague. Take that back. I guess it could say just "error." I don't even get to the boot prompt which limits what I can do. I cannot boot into rescue mode. I tried boot-repair, but it took more than 24 hours to check the system configuration, so I gave up on that. I'm running a Mac Mini with its main OS being Mac OS X 10.5.8. I have an alternate OS Windows XP installed, which was virtually destroyed by this Linux installation. I sacrificed my working, speedy Windows partition for something that won't even boot up. What was I thinking. My Mac partition is slow as crap. I've tried installing 12.04 many times with two different disks. The first time, I had one partition for Linux, then I had 2 (swap+main), then 3 (swap, main and BIOS), then 4 which is what I have now (swap, main, BIOS, and boot/grub). The only way I could get through the install without GRUB giving up was if I created a separate partition for it. Which was pointless, because it did install successfully, but it still doesn't boot up at all. Could rEFIt be booting off of the BIOS or one of the other partitions? Because if that's the case, there is no alternative, because Mac itself without rEFIt refuses to recognize a Linux ext4 (or 2 or 3) format partition. Apple always has to make everything so difficult. If I'm not mistaken, rEFIt is the only application of its kind for Mac. I can boot off of the CD back to the install/try screen. This is extremely upsetting, can you guys help? Please?

  • Pointer position way off in Java Application menu's when using gnome-shell

    - by Hailwood
    When using any java application in gnome-shell if the window is maximised the pointer position is way off; but only on the menu's, in the editor, or the side panel, the pointer is fine. This only presents itself when the window is maximized, and it seems that the further away from 0x0 the window is when you maximise it, the bigger the pointer offset. From what I have gathered it has to do with the window not updating it's size when it gets maximised. The other issue is that when a gnome-shell notification appears, when clicking on it, I lose the ability to type in the editor, I can select text etc, but can't give it focus to type. I must bring up some other text input (e.g. right click on a file on the left, select rename, which brings up a rename dialog) after that I can type in the editor again. So, how can I fix this? Below is as much information as I can think to provide $ gnome-shell --version GNOME Shell 3.6.1 $ java -version java version "1.7.0_09" Java(TM) SE Runtime Environment (build 1.7.0_09-b05) Java HotSpot(TM) 64-Bit Server VM (build 23.5-b02, mixed mode) $ file /etc/alternatives/java /etc/alternatives/javac /etc/alternatives/java: symbolic link to '/usr/lib/jvm/java-7-oracle/jre/bin/java' /etc/alternatives/javac: symbolic link to '/usr/lib/jvm/java-7-oracle/bin/javac'

  • Kingston SD reader not working for USB3

    - by user1146334
    I have a Kingston 4-in-1 Multimedia reader. When my PC was formatted with Win7 it worked fine. I decided to change to Ubuntu 14.04 and now it doesn't work.

  • How to change system time or force a time sync

    - by cpury
    My laptop is probably running out of CMOS battery, I know I have to fix it soon, but until then, this very annoying issue keeps me from using it. Scenario: My system clock is reset to 15/12/08 11:00 AM every time I turn on my computer. This has all sorts of side-effects, one of the more annoying being that I can't log into my gmail. At first I just waited for a time sync to happen, as I have that activated and all. It never happened. I googled and didn't find any way of enforcing a time sync, which I found very strange. Is there really none? Setting the time and date by hand is also a problem. For my 12.10 installation, the time & date settings are bugged. I remember it being for my last, older installation as well, though. Of course the easiest way should be to just manually edit the date and time fields by entering a new date. This is possible in theory, but the changes are reverted as soon as the text boxes loose focus. The other way to do it is to click the +-buttons for a long, long time. The first time I did that, the changes weren't stored either. I found out that afterwards I have to switch from manual to internet-sync mode and wait ~5 seconds until the in the top left corner of my system the new time is shown, or otherwise it won't have effect. So a nice solution would be one of the following: Setting the time/date by hand, maybe via terminal, so I can just enter the right values. Or, a command that would enforce an immediate time sync, that I can run after booting. I know I have to change the batteries soon, but this is seriously keeping me from working...

  • Can't ssh to instance

  • Bluetooth headset A2DP works, HSP/HFP not (no sound/no mic)

    - by Stefan Armbruster
    My Philips SBH9001 headset pairs fine using Ubuntu 12.04. In the audio settings it's properly detected as A2DP device and as HSP/HFP device. Hardware: Thinkpad X230, Ubuntu 12.04 64bit, Kernel 3.6.0-030600rc3-generic (build from Ubuntu mainline repo), Bluetooth device is USB-Id 0a5c:21e6 from Broadcom, Headset is a Philips SBH9001. Note: Kernel 3.6 rc3 is used because of a fix for audio on the dockingstation that is not in any previous branches. Playing audio in A2DP works just fine out of the box, but when switching the headset to HSP/HSP mode there is no sound nor does the microphone work. When connecting the headset, /var/log/syslog shows: Aug 25 21:32:47 x230 bluetoothd[735]: Badly formated or unrecognized command: AT+CSRSF=1,1,1,1,1,7 Aug 25 21:32:49 x230 rtkit-daemon[1879]: Successfully made thread 17091 of process 14713 (n/a) owned by '1000' RT at priority 5.

  • Using HTML5 Today part 2&ndash;Fixing Semantic tags with a Shiv

    - by Steve Albers
    Semantic elements and the Shiv! This is the second entry in the series of demos from the “Using HTML5 Today” talk. For the definitive discussion on unknown elements and the HTML5 Shiv check out Mark Pilgrim’s Dive Into HTML5 online book at http://diveintohtml5.info/semantics.html#unknown-elements Semantic tags increase the meaning and maintainability of your markup, help make your page more computer-readable, and can even provide opportunities for libraries that are written to automagically enhance content using standard tags like <nav>, <header>,  or <footer>. Legacy IE issues However, new HTML5 tags get mangled in IE browsers prior to version 9.  To see this in action, consider this bit of HTML code which includes the new <article> and <header> elements: Viewing this page using the IE9 developer tools (F12) we see that the browser correctly models the hierarchy of tags listed above: But if we switch to IE8 Browser Mode in developer tools things go bad: Did you know that a closing tag could close itself?? The browser loses the hierarchy & closes all of the new tags.  The new tags become unusable and the page structure falls apart. Additionally block-level elements lose their block status, appearing as inline.    The Fix (good) The block-level issue can be resolved by using CSS styling.  Below we set the article, header, and footer tags as block tags. article, header, footer {display:block;} You can avoid the unknown element issue by creating a version of the element in JavaScript before the actual HTML5 tag appears on the page: <script> document.createElement("article"); document.createElement("header"); document.createElement("footer"); </script> The Fix (better) Rather than adding your own JS you can take advantage of a standard JS library such as Remy Sharp’s HTML5 Shiv at http://code.google.com/p/html5shiv/.  By default the Modernizr library includes HTML5 Shiv, so you don’t need to include the shiv code separately if you are using Modernizr.

  • sublime text 2 review !

    - by Anirudha
    Few months ago I am looking for a editor to doing simply edit on html,css,javascript.  Before it I tried notepad++ which is quite awesome to do all works I want to get done with him.  I choose 2 editor on my list. first is sublime text and second is phpstorm. both are cross-plateform. I tried both and both is working fine. I finally go with sublime text 2.   Here is the reason why sublime text 2 is awesome. phpstorm and sublime text 2 both is licensed  software. In sublime text 2 you can use it for unlimited time when phpstorm is available for 30 days only. Sublime text 2 is very memory efficient and lightweight software this is first thing people found best in sublime text 2. in phpstorm problem for me is sometime it’s goes unresponsive when I tried html5 boilerplate. sublime text 2 is never hang depend on memory size of project compare to phpstorm. in Sublime text 2 you can got better speed at coding after learning some shortcut and basic thing applied specially sublime text 2. Sublime text 2 come with distraction free mode when phpstorm have nothing with full-screen. Sublime text 2 support almost every language.

  • Can't boot into windows7/ubuntu 12.04 after running boot-repair

    - by Rini
    I have installed Ubuntu 12.04 on my preinstalled windows 7 Sony vaio E series laptop following instructions here: http://www.linuxbsdos.com/2012/05/17/how-to-dual-boot-ubuntu-12-04-and-windows-7/ Everything went well and I am able to boot in to windows after complete installation of Ubuntu. Now following instructions on web I tried to add Ubuntu to my BIOS using Easy BCD (but forget to add windows 7 entry). As a result, I loose windows 7 OS and can't boot in to either OS then I successfully repaired windows 7 using recovery CD. Now my problem is that I can't reinstall Ubuntu 12.04 using Live CD it halts every time before disk partition step giving error. "ubi-partman crashed". "ubi-partman failed with exit code 141. further information may be found in /var/log/syslog. Do you want to try running this step again before continuing? If you do not, your installation may fail entirely or may be broken." and, any choice to continue will result in the same error. After that following some post solutions I ran boot-repair commands in terminal ( in Try Ubuntu mode) and got the following URL: http://paste.ubuntu.com/1206434/ Now, after restart I can't boot into either Windows or Ubuntu. Even any attempt to run Windows repair is failed and I got the message : 'No operating System found' I don't know what went wrong after running boot-repair command. Please help in solving this issue. Thanks and Regards, R Shukla

  • mdadm: breaks boot due to "is not ready yet or not present" error

    - by BarsMonster
    This is so damn frustrating :-| I've spent like 20 hours on this nice error, and seems like dozens of people over Internet too, and no clear solution yet. I have non-system RAID-5 of 5 disks, and it's fine. But during boot up it says that "/dev/md0 is not ready yet or not present" and asks to press 'S'. Very nice for Ubuntu Server - I have to bring monitor and keyboard to go next. After this system boots and it's all fine. md0 device works, /proc/mdstat is fine. When I do mount -a - it mounts this array without errors and works fine. As a dumb and shameful workaround I added noauto in /etc/fstab, and did mounting in /etc/rc.local - it works fine then. Any hints how to make it work properly? fstab: UUID=3588dfed-47ae-4c32-9855-2d69df713b86 /var/bigfatdisk ext4 noauto,noatime,data=writeback,barrier=0,nobh,commit=5 0 0 mdadm config: It is autogenerated: # mdadm.conf # # Please refer to mdadm.conf(5) for information about this file. # # by default, scan all partitions (/proc/partitions) for MD superblocks. # alternatively, specify devices to scan, using wildcards if desired.

  • Using gluLookAt to move camera in 2D iPhone game ?

    - by Mr.Gando
    Hey guys, I'm trying to use gluLookAt to move the camera in my iPhone game, but every time I've tried to use gluLookAt my screen just goes "blank" ( grey in this case ) I'm trying to render a simple triangle and to move the camera, this is my code: to setup my scene I do: glViewport(0, 0, backingWidth, backingHeight); glMatrixMode(GL_PROJECTION); glLoadIdentity(); glRotatef(-90.0, 0.0, 0.0, 1.0); //using iPhone in horizontal mode glOrthof(-240, 240, -160, 160, -1, 1); glMatrixMode(GL_MODELVIEW); then my "triangle rendering" code looks like: GLfloat triangle[] = {0, 100, 100, 0, -100, 0,}; glClearColor(0.7, 0.7, 0.7, 1.0); glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT); glEnableClientState(GL_VERTEX_ARRAY); glColor4f(1.0, 0.0, 0.0, 1.0); glVertexPointer(2, GL_FLOAT, 0, &triangle); glDrawArrays(GL_TRIANGLES, 0, 6); glDisableClientState(GL_VERTEX_ARRAY); This draws a red triangle in the middle of the screen, when I try to apply gluLookAt ( I got the implementation of the function from Cocos2D so I asume it's correct ), i do: glMatrixMode(GL_MODELVIEW); glLoadIdentity(); gluLookAt(0,0,1,0,0,0,0,0,1); // try to move the camera a bit ? GLfloat triangle[] = {0, 100, 100, 0, -100, 0,}; glClearColor(0.7, 0.7, 0.7, 1.0); glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT); glEnableClientState(GL_VERTEX_ARRAY); glColor4f(1.0, 0.0, 0.0, 1.0); glVertexPointer(2, GL_FLOAT, 0, &triangle); glDrawArrays(GL_TRIANGLES, 0, 6); glDisableClientState(GL_VERTEX_ARRAY); This leads me to grey screen (glClearColor is grey), I've tried all sort of things and read what I've found about gluLookAt on the net, but no luck :(, if someone could explain me or show me how to move to move the camera in a top-down fashion ( zelda, etc ), I would really appreciate it. Thanks!

  • How do I work around sudo 'segmentation fault' on basic bash commands?

    - by sage
    I am sure the answers are out there, but alas there are too many answers (here and elsewhere) to other questions stopping me from finding them. I just encountered something substantially similar to what is described at the closed SO question, sudo : “segmentation fault” Ubuntu maverick [closed]. My team is using Ubuntu 11.04 on VMWare Workstation 8.0.4. We are doing development using c++, Xenomai, Qt, and Qt Creator. When we simulate our application on the virtual machine, we currently need to launch Qt Creator with sudo. My colleague mentioned today that he has been having issues where his workstation locks up and he needs to restart and that occasionally he has the issue that all sudo bash commands return "segmentation fault". I just ran our application in simulation mode. I was running Qt Creator under sudo and Qt Creator received the signal abort (if I recall). Afterward, every command executed with sudo from sudo qtcreator to sudo ls resulted in the message Segmentation fault. I clicked on the power widget to see if I could log out, but the system shut down straightaway without prompting. My understanding is that we run sudo because of a permissions issue with Xenomai and the VM as currently configured, but my colleague has a workaround for this. I expect that not running Qt Creator under sudo -- something that has always made me nervous -- will help contain this issue, but I find it troubling that this could happen and manifest as it does. Does anyone know what is happening? Any recommendations on how to work around this issue? This is happening often to I am trying tolobby for VM changes to be able to run the process without sudo.

  • Got a Great Solaris Story to Tell? Come to OpenWorld and Tell It

    - by Larry Wake
    I know there are a lot of Solaris veterans that still haven't experienced the enormousness that is Oracle OpenWorld. Simply put: if you have a chance to go, you should go. You'll learn a lot, and you'll be in one of the greatest cities in the world at the same time. Even better: if you've got something to share, we might be able to get you in for free. Yep, it's that time already: the Call for Papers for this year's OpenWorld (and JavaOne) is open.  But not for long -- you've only got until April 9th to submit your abstract. As a Solaris person, you'll probably be most interested in participating in one of two tracks: SERVER AND STORAGE SYSTEMS: Oracle Solaris ORACLE DEVELOP: Oracle Solaris and Oracle Linux Development All you need to give us right now is a title and an abstract. If your session is accepted, we'll let you know by early June, and you can start to plan to join us in San Francisco from September 30 to October 4. (If you're planning on attending in listen-only mode, be aware that the early registration price is available until March 30.) As is true every year, this is your opportunity to meet the leading Oracle hardware and software engineers, including lots of the Oracle Solaris team, and interact with your peers from all over the world. See you there!

  • What is the best way to code the XNA Game Server for FPS game?

    - by AgentFire
    I'm writing a FPS XNA game. It gonna be multiplayer so I came up with following: I'm making two different assemblies — one for the game logic and the second for drawing it and the game irrelevant stuff (like rocket trails). The type of the connection is client-server (not peer-to-peer), so every client at first connects to the server and then the game begins. I'm completly decided to use XNA.Framework.Game class for the clients to run their game in window (or fullscreen) and the GameComponent/DrawableGameComponent classes to store the game objects and update&draw them on each frame. Next, I want to get the answer to the question: What should I do on the server side? I got few options: Create my own Game class on the server, which will process all the game logic (only, no graphics). The reason why I am not using the standart Game class is when I call Game.Run() the white window appears and I cant figure out how to get rid of it. Use somehow the original XNA's Game class, which is already has the GameComponent collection and Update event (60 times per second, just what I need). UPDATE: I got more questions: First, what socket mode should I use? TCP or UDP? And how to actually let the client know that this packet is meant to be processed after that one? Second, if I is going to use exacly GameComponent class for the game objects which is stored and process on the server, how to make them to be drawn on the client? Inherit them (while they are combined to an assembly)? Something else?

  • Configuration tools for multiple monitors for X / Linux

    - by richard
    I have Ubuntu 10.04 running gnome and two monitors. I am wondering if a can get a better multi-monitor configuration tool. The one I have, gnome-display-properties, has too many problems, including: When I swapped my monitors over, the narrower (external) one now on the left. There is a width calculation error, such that I have a virtual monitor the width of the wide-monitor on the narrow-monitor and part of the wide monitor. And a virtual narrow-monitor on the remainder of the wide-monitor. Also the visible mouse pointer does is not aligned with the active spot, an x offset of one monitor width. I would like, in approximate order of importance: nobugs. to be able to select which is primary monitor. to have multiple configurations. configurations to be automatically selected based on which monitors are attached. configurations to be cycled (reliably) when display mode key is pressed. when a display is deactivated, for windows to migrate to remaining monitors. option to not change display resolution when mirroring, but to use side/top blanking bars to pad out screen.

  • Dot Matrix printers setup...

    - by Parhs
    Hello! I am using debian which is similar to ubuntu. They have 7 dot matrix printers some very old like this one http://www.omnidatasys.net/product/desc_printer_ti880.htm which works from 1979 daily and at text is faster than many inkjects. I believe that it has his own language... Sending text to serial port (port server) prints garbage. However i think is prints only capital english up to 95 asccii and greek and the rest up to 127 i think greek capital.(special chip ) Sending english capital letters prints garbage i think but i amnt sure... i will try again... The other printer are ESC/P compatible and i use generic epson driver provided from ghostscript... However i think that sending text via lp -dpr1 filename It prints the text as a grafic...Changing from printer font face(courier,times roman etc) or pitch has no effect... I am wondering if is there any work arround for this? In AIX they claim that lp command printed output as text as it prints and cobol programs send raw text to to lp printers . However in AIX they use some custom filters for the printers and has more options for dot matrix printers.. I would like to know if there is a solution for this.. To avoid graphics mode for text and change font face somehow.. The most Straight-through approach would be to use no driver ,just send ESC/P from cobol but this requires too much work... Thank you again!

  • Can't enable wireless lan on Fujitsu Siemens A1665G with Ubuntu 11.10 installed

    - by Theo
    I saw my old Notebook yesterday and wanted to make that work again. On Windows XP the wireless worked still fine. Then I installed new Ubuntu 11.10 32bit and I'm sadly not able to make the wireless enabled. [I replaced Win XP entirely] lspci lists following network: 08:0a.0 Network controller: Broadcom Corporation BCM4318 [AirForce One 54g] 802.11g Wireless LAN Controller (rev 02) So after recommendation from this link I installed the b43 firmware module. iwconfig prints the following: wlan0 IEEE 802.11bg ESSID:off/any Mode:Managed Access Point: Not-Associatd Tx-Power=off Retry long limit:7 RTS thr:off Fragment thr:off Power Management: off As you can see, my wireless lan adapter is not turned on. sudo iwconfig wlan0 txpower auto Doesn't change anything. Then I tried to make it work with rfkill. rfkill list 0: phy0: Wirless LAN Soft blocked: no Hard blocked: yes sudo rfkill unblock all rfkill list 0: phy0: Wireless LAN Soft blocked: no Hard blocked: yes remains the same. The question is now, how I could enable the hard blocked wireless LAN. There is no hardware switch for wlan integrated. However there is a button to change the state. I always thought this would be software sided, but it seems to make some hardware changes as well... The wireless LED is also not blinking (as it did on windows xp) I reset bios and searched for some settings in there, but it has only a few options and nothing to do with wireless settings, nothing works here.. At last I tried to install the acer hotkeys but I was not able to manage that. I installed the acerhkgui package, but in initializing progress, it was not able to compile acer hotkeys for my machine. There was a message that asm/linkage.h was not found while compiling. Do you have any ideas what I could do to make this hard blocked stuff disabled and my wireless card work? PS: I also tried sudo rm /dev/rfkill and a reboot to reinit that stuff... No success :(
