• Ubuntu 14.04: Fine tuning Touchpad for ThinkPad S431

  - by ramgorur

  I am using Ubuntu 14.04 on Lenovo ThinkPad S431. The touchpad is very bumpy, tricky to use. Slides down with a small touch, sometimes jerks erratically. I have tried to modify the settings in /usr/share/X11/xorg.conf.d/50-synaptics.conf file as below -- Section "InputClass" Identifier "touchpad catchall" Driver "synaptics" MatchIsTouchpad "on" MatchDevicePath "/dev/input/event*" Option "JumpyCursorThreshold" "250" Option "VertResolution" "100" # Option "HorizResolution" "65" # Option "MinSpeed" "1" # Option "MaxSpeed" "1" # Option "AccelerationProfile" "1" # Option "AdaptiveDeceleration" "8" # Option "ConstantDeceleration" "1" # Option "VelocityScale" "128" Option "HorizHysteresis" "150" Option "VertHysteresis" "150" EndSection There are lots of options here, does anyone know how to get a fine-tuned values for the above options (for ThinkPad S431)? The Hysteresis values seems to alleviate the problem a little bit, but failed to get a perfect result. EDIT: According to this bug report for ThinkPad X230 (+X230t), I set these values and quite good for now -- Option "VertResolution" "100" Option "HorizResolution" "65" Option "MinSpeed" "1" Option "MaxSpeed" "1" Option "AccelerationProfile" "2" Option "AdaptiveDeceleration" "16" Option "ConstantDeceleration" "16" Option "VelocityScale" "32" Option "HorizHysteresis" "50" Option "VertHysteresis" "50" and then you need to increase the cursor speed manually from the Unity mouse settings. But I am still looking for a fully functional (possibly with all the gestures) and a fine-tuned touchpad settings for S431. Further help is appreciated.

• How to debug a fatal system crash - [graphical loop DOTA2]?

  - by Huw

  Whilst playing DOTA2, I occasionally and apparently randomly seem to be experiencing a fatal crash where the display freezes fixed and the audio loops over approx the last .5 of a second. Now, I'm interested in resolving this - but my trouble is I don't know where to start. The error appears non-reproducible (I've tried returning to games and deploying the same combination of events in hopes of pinning to to a certain shader etc), and I don't know which part of 'the stack' it might be coming from. Variables that occur to me: I custom build this system, did I do something wrong - is my PSU not providing enough power to the graphics card? I am running Steam and DOTA under Linux, could this new software have a bug Might it be something to do with my ATI Catalyst graphics drivers Is some other background process interfering I'm usually mid game when this occurs, so i quickly kill the power and reboot (when i'm lucky i can get back in with only 1-2 mins lost!). So my question here relates to logs. Where should I start to look or how might I set up logs to help me pin down a fatal crash of this kind by recording moments up to / before a crash and is this likely to be something I should push Steam to do, or is there something at a system level? Then perhaps I can return with a more specific question and perhaps even a bug report :) Many thanks in advance.

• Ubuntu 14.04 Unity not functioning, no launcher

  - by user216962

  Yesterday I turned my computer to find that the launcher was missing. In addition, I could not using ctrl-alt-t would bring up a blank white screen. The only terminal could be found by clicking ctrl-alt-f1. I used ccsm to turn on Unity. Unity panel service was working. I installed tweak tool. I did all the troubleshooting I could find related to this subject. Nothing would work. I ultimately reinstalled Ubuntu 13.10. Also, I do not have an nvidia graphics card. I have an intel integrated graphics controller. Some of the troubleshooting I tried were found: Unity doesn't load, no Launcher, no Dash appears ubuntu 14.04 unity desktop without panel and launcher how to fix: no unity, no launcher no dash in ubuntu 14.04 http://ubuntuforums.org/showthread.php?t=2008891

• How to protect Ubuntu from fork bomb

  - by dblang

  I heard someone talking about a fork bomb, I did some research and found some dreadful information about some strange looking characters people can have you type at the command line and as a result do bad things on the computer. I certainly would not issue commands I do not understand but one never knows what can happen. I heard that some OS allows the administrator to place some limit on user processes to mitigate the effects of fork bombs, is this protection in Ubuntu by default or would a person with sudo privilege have to set this? If so, how?

• Override Built-In Maverick Keyboard Shortcuts

  - by jrc03c

  Having used the Command+M keyboard shortcut to minimize windows in OS X, I'd like to use the same functionality in Ubuntu 10.10. When I try, though, it only brings up the "communications" section of the indicator applet; like so: In the Keyboard Shortcuts preferences, I have set as the minimize shortcut "Mod4+M", which I got by capturing the Apple "Command" key and the "M" key. I find no other shortcut using this key combination in Keyboard Shortcuts, and yet I cannot get the window to minimize when using it. Does anyone know how to override Ubuntu's default usage of this key combination? Thanks!

• Compiz: How can I pin osd-lyrics to the Desktop?

  - by joebuntu

  Hey ya, I have certain applications pinned to my desktop. such as Rainlendar (1), which offers this option in the settings window conky (2), with "own_window_type normal" in my ~/.conkyrc Rhythmbox's Desktop Cover Art plugin (3), a python plugin sticked to the desktop. They all hide nicely below all other Windows. I set Compiz to not minimize them on "show desktop" command using "window rules". I also use [osd-lyrics][1] to display music lyrics. It's default behaviour is to stick always on top, which is irritating sometimes and, in my case, looks rather fugly. (4) See screenshot at: http://i.imgur.com/ie16K.jpg Now how can I tell Compiz to pin the osd-lyrics bar to the desktop below all other windows and not minimize it? I tried all sorts of window rules and exceptions, e.g. using "class=osd-lyrics", "title=osd-lyrics" but the OSD doesn't seem to match any of these. Any ideas? Running: Ubuntu 10.10 Maverick Meerkat, Compiz 0.8.6, osd-lyrics 0.3 from code.google.com/p/osd-lyrics

• Battery charging is flickering [closed]

  - by Michael

  A few days ago my notebook started to bug around with charging the battery. When the battery is not absent notebook runs smoothly. Until I plug in the battery. Then it starts to charge but immediately stops and restarts charging and stops and so on. If the notebook is not running battery seems to charge well (LED is not blinking). And LED is not blinking intermittently. Seems to be arbitrary. Does it have something to do with that? This happens every second. [13354.078696] keyboard: can't emulate rawmode for keycode 240

• SSH Lost Terminal Colors

  - by memecs

  I have to computers with exactly the same configuration (same PS1 etc...). When I ssh from A to B the terminal correctly displays PS1 and file type colors (i.e. blue directories, green executables etc.) But when I ssh from B to A PS1 is set to default and colors disappear. Furthermore, I created public keys to ssh without password from A to B and vice-versa. It works correctly from A to B but it doesn't work from B to A, again I repeated the exact same procedure on both pc: On Host A ssh-keygen ssh-copy-id -i ~/.ssh/id_rsa.pub address.to.host.B On Host B ssh-keygen ssh-copy-id -i ~/.ssh/id_rsa.pub address.to.host.A What could be the problem?

• Ubuntu 12.04 won't shut down - stopping winbind daemon

  - by jan

  My Precise Pangolin sometimes won't shut down - the screen is black with text on it. Mostly last line says something like "stopping winbind deamon" (sometimes also virtualbox, which is above winbind daemon; edit: sometimes the last line says "running unattended updates") and it stays like this for about ten miutes. Then I usually hold the power button for 5s to shut it down. It's very unpredictable - sometimes the computer shuts down without problem and sometimes it hangs. I've tried many ways to shut it down: HW button, panel applet, sudo shutdown -h now, sudo poweroff, sudo halt, etc. even sudo reboot or restart from panel applet have this problem. Sometimes it works ok but every method named hung at least once on the same (damned) line. My specs: FUJITSU SIEMENS LIFEBOOK E8310, Intel Core2 Duo T7300 @ 2.00GHz, 3GB RAM, GPU: Mobile Intel(R) 965 Express Chipset Family Ubuntu 12.04.2 32bit, 3.5.0-41-generic kernel (but it did it on older kernels and 12.04.x systems too). Any ideas what should I try next? Thanks a lot! Jan

• Hibernation is still missing from menu in 13.10 after enabling via polkit. How to enable?

  - by LiveWireBT

  I know that since 12.04, we need to add a policykit rule to enable hibernation (see question How to enable hibernation? and the Official Documentation). I can successfully bring my laptop into hibernation mode with sudo pm-hibernate or sudo s2disk, so the rule is in place and works, but the hibernation entry is still missing in the menu. I can tell from looking through the source of the indicator-session package (but not understanding the whole code) that there is still a hibernation menu entry in the code and it should be displayed when the system is capable of hibernating. Please calm down if you're enraged by this. This is very unlikely to be a conspiracy, but rather a bug/regression on a deeper level, which can happen when you move code around or replace it. Question: What needs to be done in 13.10 to properly tell indicator-session that the system can hibernate? Possible duplicate: Hibernation still not available - No activity, because saucy was in development at that time, so out of scope for AskUbuntu. Related bug report: https://bugs.launchpad.net/ubuntu/+source/indicator-session/+bug/1232814

• Horizontal title bar shadow while in full screen

  - by Atcold

  While in full screen the horizontal shadow of the title bar (I am not too sure about its name) appears on top of everything. How can I get rid of it? It's quite distracting while coding in Guake mode and annoying while watching movies. In the picture I've setup Guake with some transparency (that's why you can see things underneath), but the shadow is on the top of everything while I am in fullscreen. This, as I have already said, happens to me both while I am watching movies or programming in fullscreen mode. This usually happens after awaking the laptop from hibernation. Now it looks like it has gone, but I am still wandering if someone knows something about it. And here back it is :[ I'm running Ubuntu 13.04

• Wireless Very slow with 13.10 and BCM4313

  - by RyanCheu

  I have a laptop with the BCM4313, and it was working perfectly in Ubuntu 13.04, but I recently upgraded to 13.10 and now my wireless performance is horrible. Initially it didn't work at all, but I removed the wl driver and use the brcmsmac driver instead. Now when I boot up it works at the start, but gets progressively slower. My Android device is reporting 10Mbps down/20Mbps up, but my laptop only gets 1up/down. Does anyone know a solution? I really need my wireless to work, is my best option to just reinstall on 13.04? Thanks!

• Non-responsive mouse and keyboard fix

  - by JacobusR

  I'm using Ubuntu 12.10 and found that after about 20 minutes of work that my mouse and keyboard became very unresponsive. So I found the following fix: sudo -i To test if this is the problem: echo N> /sys/module/drm_kms_helper/parameters/poll To make the fix permanent: echo "options drm_kms_helper poll=N">/etc/modprobe.d/local.conf It appears that the fix does work, but what does this do? Am I breaking something else in doing this?

• Lost sudo privileges

  - by Gamegoofs2

  Last night I was working on installing vsftpd on my Ubuntu 12.10 server. I shutdown last night and when I booted up this morning I seemed to have lost the abilities to sudo anything. It just says, "** is not in the sudoers file. This incident will be reported." Now I wasn't messing with any sudo files, just /etc/vsftpd.confg and /etc/shells. So how did I seemingly lose sudo ability? I'm rather new to Linux in general, but I'm picking it up quick.

• Terminal doesn't see Windows filesystem until I open in Home Folder GUI

  - by yeenow123

  I'm currently dual-booting Windows 7 and Ubuntu. When I try to access my Windows HD through the terminal I can't find it. However, I used the Home Folder application to see where those drives/folders were. And after I clicked into it in the Home Folder, I looked again at the same folder in the terminal and it appeared. Is there a reason for this and how can I set it so I always can see those folders?

• Boot time seems unusually long on MSI GX660R (bootchart included)

  - by Sman789

  After upgrading (clean install) to Ubuntu 12.04, the speed issue when running programs has reduced on my MSI GX660R laptop. However, the boot time is still much longer (over a minute, even after BIOS) than on the many less powerful laptops I have encountered running the same OS, and I was wondering if anyone could help me improve it. I use the FGLRX driver, if that makes any difference. I have uploaded a boot chart, it can be found here http://imageshack.us/photo/my-images/4/bootchartl.png/ As you can see, the boot time is over a minute even after BIOS. A 'designed for Vista' laptop from ages ago which I installed Ubuntu on boots in around thirty seconds, so I think it's a bit strange.

• Setup suspend-on-lid-close/Fn+F4 outside of KDE/Gnome?

  - by maxschlepzig

  On current Ubuntu (10.04) suspend-on-lid/Fn+F4 only works if some powermanagement-applet of KDE/gnome is running. But what about suspend-to-lid if you are working on the console or using a non-bloated window-manager? What is the current mechanism to configure suspend-on-lid system wide? What of hald/udev/acpid/foo-kit/random-thing is the right place to hook this feature in? What is the up-to-date command to suspend from the command line/script? echo -n mem > /sys/power/state pm-suspend pmi or something else? Btw, if it matters, I want to configure it on some Thinkpads.

• Remapping Alt + F2 in Unity

  - by Jesse

  I disabled the Alt + F2 default shortcut in unity (ubuntu 11.10) using ccsm and I set a new shortcut using the default system shortcut manager (system settings keyboard). And it works, until I execute a command like compiz --replace. After that, all shortcuts keep working normally, except for Alt + F2. It does nothing. Any suggetions to keep the custom Alt + F2 shortcut working after compiz --replace?

• Display artifacts under Ubuntu 12.10

  I am getting some display artifacts under a fresh install of 12.10. (Open image in an another tab to get the full effect) Anyone have any idea what might be going on here or a possible solution? My first assumption was display driver, but I've been have some difficulties getting the Nvidia binary driver to work. So I wanted to check for other possible solutions before I spend a lot of time messing with getting that to work.

• Why does update-grub not find ubuntu 11.10?

  - by Klaynos

  I've recently installed ubuntu onto my laptop. With the intention of dual booting with windows 7. On installation Grub wasn't loading, the computer continued to boot straight into windows. I loaded a live cd, mounted the installed ubuntu partion (sda6) as /mnt/ and windows boot partition as /mnt/boot Following the second option here: http://ubuntuguide.net/how-to-restore-grub-2-after-reinstalling-windows-xpvistawin7 Through its entirety, so creating a new grub.cfg file. chroot /mnt update-grub Did not find ubuntu, just windows 7 and the windows recovery partition. Thinking this might be a weird quirk that as I was in ubuntu (all be it a live cd) it might not list ubuntu I restarted. Grub loaded but ubuntu was nowhere to be seen. How can I add ubuntu with Grub2? I could have fixed this myself in old grub but I'm pretty much in the dark here. Thanks
