This may be the cause of your problems: Nvidia-Prime Freeze Theese two things have worked for me so far; either: Disable touchpad in: System settings -> Mouse & Touchpad -> "off" and use a regular USB mouse. Install nvidia-prime sudo apt-get install nvidia-prime, find "Nvidia Settings" in dash, and under "Prime Profiles" choose "Intel(Power saving ...

I had EXACTLY the same problem with NVIDIA drivers. Your problem probably is related to these bugs (they all have the same symptoms): https://bugs.launchpad.net/ubuntu/+source/nvidia-graphics-drivers-319/+bug/1220426 https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1310762 http://bugs.launchpad.net/ubuntu/+source/xorg/+bug/1314871 Unfortunately it is ...

It sounds like issues with your graphics driver. Is this happening right after the install or after you install a proprietary driver? I had this issue after installing a prop. driver and switching my monitor from the integrated graphics port my gpu. I know if you have an ATI driver, you are going to have to use the integrated graphics to install Ubuntu, and ...

According to your dmesg output there's a bug in the WiFi driver. Let's take a closer look: the most recent wakeup event is at [22500.127146] ACPI: Waking up from system sleep state S3 and the wakeup finishes ~5 s later: [22505.833530] PM: Finishing wakeup.

You can disable that feature : Install Unity Tweak Tool, a program that will help you configure Unity : sudo apt-get install unity-tweak-tool Open it and go to Windows Snapping, and switch it off.

To debug more, I advise to change the boot options so that the boot is more verbose. If you edit (as root, with gksudo gedit /etc/default/grub) you can see a line somewhere with is similar to: GRUB_CMDLINE_LINUX_DEFAULT="quiet splash" remove "quiet" (or the two of them to have an old-style, no graphic, verbose boot) and save. Then you have to run sudo ...

If the DE has frozen, switch to a different run-level by using ctrl-alt-f3 and login to the terminal presented. You can kill any offending processes by using kill or killall, if the DE has gone into hardlock it may be worthwhile to kill xorg by sudo killall Xorg to restart the DE (usually drops you back to the DM to login),switch back to the graphic ...

You will probably have set some incompatible setting combination(s). Gnome Tweak Tool can be used on Ubuntu, but is not exclusively for Ubuntu + Unity. That is why there is no "set to default" option, like you would expect from an application, dedicated to Ubuntu only. Removing the application would not undo the setting changes you made with it. Since you ...

Applications freezing and no Launcher could both be caused by trying to install Ubuntu on a computer that does not meet the minimal system requirements for it. Ubuntu publishes Release Notes for each official Ubuntu derivative that it releases, which can be easily found by searching for something like "Ubuntu 13.10 release notes" for your particular version. ...

I know this question is old, but I had this problem in Ubuntu (Chrubuntu) 14.04 on an Acer C720 Chromebook. I tried Krišjānis Nesenbergs solution, and it worked somewhat, but still crashed sometimes. I finally found a solution that worked by installing zram instead of using physical swap on the SSD. To install it I just followed the instructions here, like ...

I had similar behaviour in 14.04: freezing screen and need to log-in after alt-tab. not always, but frequently enough to be annoying. Seems to be solved now: Installed compiz config Under 'desktop', swithed off the Ubuntu Unity Plugin, directly re-enabled this plugin Compiz now complained about a conflict ('Show desktop plug-in', if I rembember well) and ...

Upon further investigation I was able to trace it down to libticalcs2-11 which was unable to update because of a unmet dependency, which made the whole upgrade process to stop, which made the system reboot with half of the new packages installed and the rest of the old ones, causing the driver issues. After removing the library and running a apt-get -f ...

Do a Memory Test & make sure your RAM's are working fine. So, I had similar issues with a heavy config like this. I thought Ubuntu is having compatibility issues with the hardware I have purchased so ignored & moved on to windows again. But recently I tried it again but the same issues were still there. The issues I had ranged from - chrome keeps ...

None. Contrary to popular belief, it is not harmful to computer at all. However, you may lost some unsaved work, but anyway most of software silently do backup copy quite frequently. There are also possibility to affect filesystems if power cut-off occurs during write operation, but every modern filesystem can deal with it and automatically fix its ...

The problem turned out to be with the kernel time processing: when I run cat /var/log/syslog | grep -i 'unstable' I see several error messages such as Clocksource tsc unstable (delta = -3474929768 ns). I solved it by turning on ACPI HPET table in BIOS. With another clocksource Linux kernel managed to handle the timers correctly.

I've seen cases like this where the problem was a bad RAM chip or a bad sector on the hard drive. Not enough to crash the system but enough to give the OS a hiccup. Run Memtest86 on the RAM, and if possible swap out the RAM for a friend's and see how it runs. Best to run the Memtest from a Live CD. Use a hard disk test utility from the HDD manufacturer ...

When you chroot into your system, regenerate your initial RAM-disk. It is likely that modules are missing causing this problem to occur. update-initramfs -k all -c Before chrooting, mount /dev, /proc and /sys inside chroot: mount -t proc /proc /mnt/proc mount -o bind /dev /mnt/dev mount -o bind /sys /mnt/sys I'm assuming here that you mounted your ...

It turned out to be a hardware problem - graphic card fan was packed with dust, and graphic-costly operations (like watching videos) caused it to overheat. I found that out when it was already too late and I needed to replace the graphic card.

Your video card drivers version should be 340.46. I am sure you can open nviida-settings and check out version, and also adjust all related power-management fields in nvidia-settings. In Kubuntu default power management, make sure you check your settings for all of the 3 sections present in there, namely AC POWER, ON BATTERY, ON LOW BATTERY. Disable Dim ...
