• UEFI hardware and dual booting with windows

  - by user39803

  I've been struggling for 3 days trying to dual boot Ubuntu 11.10 and Windows 7. I want to use an SSD for my Ubuntu installation and an hdd for Windows. I realized that I have to install windows first and then ubuntu, and so I did that. When I first install windows it boots fine from my hdd, but when I add ubuntu on my ssd and restart, I get a black screen with a blinking cursor. I've read many forums where this is asked but haven't found a single solution that works. I've tried boot repair. It told me to make a fat ESP partition and I did that as well but it still doesn't work. I'm a noob and any suggestions would be really appreciated.

• How to disable VGA

  - by Bitmap

  If i run lspci | grep VGA I get below output which tells me below VGA cards are present on my computer. 01:00.0 VGA compatible controller: nVidia Corporation GT216 [GeForce GT 220] (rev a2) 08:02.0 VGA compatible controller: ATI Technologies Inc ES1000 (rev 02) The ES1000 is an onboard card which came with my machine. Do anyone know how to disable this VGA on my machine. The reason for this request is because if I run xrandr I get the output as shown below: xrandr: Failed to get size of gamma for output default Screen 0: minimum 320 x 240, current 1024 x 768, maximum 1024 x 768 default connected 1024x768+0+0 0mm x 0mm 1024x768 50.0* 800x600 51.0 52.0 53.0 680x384 54.0 55.0 640x480 56.0 512x384 57.0 400x300 58.0 320x240 59.0 Which means I am not able to configure nVidia to accept smaller resolution. Thank you.

• How do I configure the mouse to raise and lower windows

  - by user288496

  I've just installed 14.04 and cannot find the congfuration screen to control how mouse clicks are acted on by the window manager, and then optionally passed to the application. I want to set the sane traditional unix behaviour of: - 'focus follows mouse': done. - 'never auto-raise': done. - 'raise when click on border or title': Can't find the option. A middle button click on the tile does lower a window - but traditionally it would also raise the botton window. I can set 'raise on any click' - but that is absolutely hopeless when you are trying to copy text from a lower window.

  - by ning

  Can I use WUBI as an offline installer? I already had the .iso file of ubuntu 12.10 - i386, and inside the iso is wubi.exe. For example: I will do a partition of, E:30gb then i will target E: in wubi so that it will be Ubuntu then use the .iso file to install it on E: My Computer: Acer Aspire 5750-6683 i5-2450m processor Is it fine to do a dual boot? Can I run Windows 7 Home Premium OS, with the custom theme and boot screen, can that effect dual booting? I just don't want to damage any of files or either any of OS And if I can't boot any of the operating systems what should I do? Can I avoid doing a clean install if that ever happens?

• mysqld - master to slave replication using rsync innodb, sequence number issues

  - by Luis

  I've read several of the related topics posted here, but I have not been able to avoid this innodb error. The steps I've taken to replicate data from a Slackware server - 5.5.27-log (S) to a FreeBSD slave - 5.5.21-log (F) were these: (S) flush tables with read lock; (S) in another terminal show master status; (S) stop mysqld via command line in third terminal; (F) while both servers are stopped, rsync mysql datadir from (S), excluding master.info, mysql-bin and relay-* files; (F) start mysqld (skip-slave) 121018 12:03:29 InnoDB: Error: page 7 log sequence number 456388912904 InnoDB: is in the future! Current system log sequence number 453905468629. InnoDB: Your database may be corrupt or you may have copied the InnoDB InnoDB: tablespace but not the InnoDB log files. See InnoDB: http://dev.mysql.com/doc/refman/5.5/en/forcing-innodb-recovery.html InnoDB: for more information. This kind of error happens for a lot of tables. I know I can use dump, but the database is large, ca. 70GB and the systems are slow (old), so would like to get this replication to work with data transfer. What should I try to solve this issue?

• Possible to map mouse coordinates to isometric tiles with this coordinate system?

  - by plukich

  I'm trying to implement mouse interaction in a 2d isometric game, but I'm not sure if it's possible given the coordinate system used for tile maps in the game. I've read some helpful articles like this one: How to convert mouse coordinates to isometric indexes? However, this game's coordinate system is "jagged" for lack of a better word, and looks like this: Is it even possible to map mouse coordinates to this successfully, since the y-axis can't be drawn on this tile-map as a straight line? I've thought about doing odd-y-value translations and even-y-value translations with two different matricies, but that only makes sense going from tile-screen.

• Ubuntu doesn't boot after upgrade

  - by Hugtrw

  I updated to 12.10 and the OS will not load. I used the boot repair cd, and the only thing that works is the monodeset option in the kernel and the graphics are terrible, mouse disappears and unity will not load. Ubuntu 12.04 ran great. On a clean install of 12.10 Ubuntu wont even load to install unless under using monodeset. I get left a terminal like screen with just a blinking bar. I'm using a HP Compaq NC6400 Laptop, Ubuntu 32-bit, 2gb ram.

• Dell monitor not detected (Ubuntu 11.10)

  - by Charles

  I have an issue with my monitor. I just installed Ubuntu 11.10, but the monitor that is plugged in doesn't appear anywhere. And by doesn't appear, I mean that in the "Displays" menu, it doesn't even appear as "Unknown", I just have my screen that appears and nothing else. It is connected through VGA, and the monitor is recognized with no problem on Windows 7. It is a Dell monitor. I'm not a pro with Ubuntu, so any help to diagnose the issue would be really helpful (and help me learn how to fix this kind of monitor issue in the future) Thanks !

• LXDE will not suspend when laptop lid is closed, and will die when woken up

  - by user46061

  I am not an experienced Linux user, although I have been using Ubuntu occassionally some time already. ( Since Feisty Fawn probably? ). Now I installed Ubuntu 11.10 and it is nice ( well, after I installed LXDE, Unity sucks and I didn't really like gnome-fallback-session ), but it has one problem: After being suspended, when I wake my computer up, it starts up and in about 5 seconds it dies. Like a normal shutdown. Then, when I start it again, the screen stays blank, so I have to hard-turn it off - only then, when I turn it on, it works. It is an MSI laptop, about 3-4 years old. The second problem is: After installing LXDE, when I close the laptop lid, it does not suspend. I can only suspend using the shutdown menu - and the waking up problem remains. Many thanks for your time and advice guys.

• No sound/audio after resuming from sleep

  - by hansvonaachen

  I've made a fresh UEFI install of Ubuntu 13.10 (64 bit) on a Lenovo Ideapad Z510 laptop with Intel i5 4200M processor. Ubuntu is the only OS installed on the computer, secure boot disabled. Everythings works fine (backlight issue fixed after editing rc.local file), the only minor trouble I have is resuming the laptop from "sleep" mode. If I close the lid and then wake the laptop opening it again, there is no audio/sound. I need to restart the computer (not even logging out helps). If I suspend the computer in a graphical way (not closing the lid): gearwheel in top right of the screen -- suspend and wake it up/turning on, audio works with no issues. Ideas how to fix this? Thanks!

• Switching to an external display, when primary is broken

  - by Shazzner

  I've successfully install Ubuntu 11.10 Desktop (x86) on an old(er) laptop that unfortunately has a broken screen, so there is an external monitor plugged in. On the livecd it come up on the secondary display just fine and I was able to install ubuntu and everything. Unfortunately when I reboot into Ubuntu proper now, the secondary display is off and I'm literally driving blind here trying to switch it to the secondary display. Using Nvidia open source drivers. Things I've tried: Rebooting back into livecd, mounting the partition and trying in vain to find a config file (it uses the open source drivers so no Xorg.conf I could edit manually) Trying to blind-type xrandr settings into what I hope is terminal: xrandr --output VGA1 --auto (nothing happened) Trying to blind install openssh-server so I could ssh into it and maybe configure it from my working computer. For some reason though, no luck. Ubuntu really should default to expanding to all screens for this use case.

• Inverted Cursor with ARM OpenJDK 7 in Chromium, and clicking issues?

  - by Espionage724

  So I have a strange issue. When using Chromium on the Nexus 7 port of Ubuntu, Java apps in the browser have the cursor flipped, literally (not just inverted movement, but the cursor itself flipped too). Also, clicking in java apps, both in the web browser and standalone, clicks don't register when using a USB mouse. I have to tap the screen itself to click. And another issue with the mouse; it seems Minecraft is unable to run, and freezes with an error similar to being unable to "GetInput", possibly related to the clicking issue above.

• How to operating systems… run… without having an OS to run in?

  - by Plazmotech Binary

  I'm really curious right now. I'm a Python programmer, and this question just boggled me: You write an OS. How do you run it? It has to be run somehow, and that way is within another OS? How can an application run without being in an OS? How do you tell the computer to run, say, C, and execute these commands to the screen, if it doesn't have an OS to run in? Does it have to do with a UNIX kernel? If so, what is a unix kernel, or a kernel in general? I'm sure OSes are more complicated than that, but how does it work? It would be really brilliant to know this! Thanks.

• kernel panic - diagnosis?

  - by user94188

  I'm having a kernel panic problem - my machine will run for hours, maybe all day and then have a panic attack. I have no idea how to interpret the output, but here's a picture of what's left on the screen when it happens: https://dl.dropbox.com/u/13279067/photo.JPG (I can't post images yet) I've looked through the logs but didn't find anything obvious - I'm still learning though so I've probably missed something. It's a little harder since it's always happened when I've been out or at night so I can't pinpoint the exact time it crashed. Anyone have advice? thanks

• Resolution problems

  - by tampe125

  i'm having some troubles with screen resolution. First of all, i'm using a Lenovo Thinkpad E520, with BackTrack 5 R2 installed. As far as I know, BT is based on Ubuntu 3.2, so I hope this is the right place to ask for help. My natural resolution is 1366x768, but I'm stuck with 1024x768. This is my hardware: lspci | grep VGA 00:02.0 VGA compatible controller: Interl Corporation 2nd Generation Core Processor Family Integrated Graphics Controller (rev 09) How can I fix that? Is there a ready-to-use driver or I have to compile that from source? At least, is there a solution, at all? :(

• Erratic display behaviour on 12.04 using an Asus Zenbook

  - by Azarias R

  When I first plugged in my 23 inch monitor through the mini-VGA port, everything worked...both display were detected, and worked. On the second or third plug in, the internal display would turn off, and only the external display would work. When I try to 'detect monitor', I got "could not set the configuration for crtc 63" a few times. Now, when I plug in the external display, I get a screen full of orange color on the external display, and the laptop display turns off. The only way to get things back is to force turn off the laptop and restart. Unplugging/replugging monitor doesn't work, and seems like ubuntu crashes. Can anyone help?

• Outbound ports to allow through firewall

  - by dunxd

  This question was asked before, but in a rather general way. I'm asking more specifically based on my current requirements. We have a number of remote offices made up of a bunch of PCs and an ASA 5505 which is used as firewall and VPN termination point. In the offices we share the internet connection with one or more other organisations over whom we have very little control, asides from the config on the ASAs. For a bunch of reasons I'd like to lock down these ASA 5505s to only allow outbound traffic to ports used by applications we know we need. I'm putting a standard config to roll out to all the ASAs, and if we need to open up ports for the other orgs we can do it on request. But I want to leave open the most commonly required ports so we can get up and running without waiting on other folks technical staff to get back. I plan to allow the following TCP ports to support commonly required resources: POP3 (110 and 995) HTTP (80 and 443) IMAP4 (143 and 993) SMTP (25 and and 465) The question really is, what other ports do I need to leave open to allow for "normal" working. I've seen UDP port 53 for DNS as one. Are there any others that would be worth opening up? Just to note - I'll also be setting up monitoring systems to keep an eye on the ports we do allow. Any of the above could be misused of course. We'll also back all this up with signed agreements. But I'm aiming for a technical solutions where I don't have to start out with the full requirements of everyone we share connections with. See also: outbound ports that are always open
