I have this problem also and so far there's no fix (if it's a bug) or a better solution without losing all the open applications. But right now the only way I can restore the whole thing without closing the applications and restarting, since I can still open a terminal (Ctrl + Alt + F1) I just do a pm-suspend which suspends the machine and just start it ...

I'm taking this discussion out of commentary and into answer mode as we are getting to a point which regards some of my expertise. When you ask if it is better to put Ubuntu "in flash drive(usb3 for max speed) and run the "try ubuntu" whenever I want?", you are discussing doing something very similar to what I do every day, except that my flash drives ...

3 possible problems: Memory HD controller (or driver) HD itself. 2 possible solutions: As grub is still working, do the MemTest86+ Take the HD out of the computer, (that way you bypass the HD controller + driver) put it in an enclosure and hook it up to someone elses Linux PC and run fsck without mounting the drive! If you need exact commands, report ...

This is a known bug. Fortunately, there is a fix now (but you'll need to compile packages yourself). See https://bugs.launchpad.net/ubuntu/+source/nvidia-prime/+bug/1220426.

It's too simple to fix. Open the terminal (Ctrl+Alt+T) sudo gedit /etc/default/grub Change...

And save. sudo update-grub sudo dpkg-reconfigure linux-image-$(uname -r) sudo update-initramfs -u And restart ...

Same problem here. I'm running a system with an Intel Celeron N2807 and Bay Trail graphics (The UCS/LIVA Bat-Mini) and when I go to wake from sleep the machine presents me with a mouse cursor and background but nothing else. I've found that if I Control-Alt-F1, then pidof X then sudo kill the process ID of the X server then it'll bring me back to a GUI login ...

This also happened to me pretty often on Minecraft and Hl2DM. I solved it by limiting the FPS to about 30. SNA UXA switching didn't work for me. I'm running Lubuntu 13.10 on Dell Vostro 3450.

I have this problem. Disabling 3D Acceleration in Bios seems to fix the problem. Press F1 or F2 on start up (or on the system settings in the grub) and disable 3D acceleration. Let me know if this fixes the problem. I have tried three or four shutdowns with no problem, but the problem might return.

I was experiencing the same problems on a laptop with GTX 860M, Ubuntu 14.04. I had the mouse cursor freeze (actually it must have been lightdm locking up) due to having the wrong graphics driver active. I had tried with the one from GeForce.com without any luck. Here is how I eventually made it work: First, make sure drivers from GeForce.com are ...

I resolved the problem by switching over to the legacy driver - version 304.117 from nvidia-304-updates.

I had a very similar issue with my 14.04 install. It would freeze for seemingly no particular reason. I blamed various pieces of software before realising it was the graphics drivers. This post I found really useful in starting me on my journey to actually having working nvidia drivers. Ubuntu 14.04 install NVIDIA driver

I got this error during the last update, so I never rebooted. To fix it, I deleted the file /etc/modprobe.d/zfs.conf since I was the one who added it and I didn't really need it. Then I ran: update-initramfs -k all -c And it now seems ready for reboot.

I was able to solve my own problem by updating the BIOS on my motherboard. I updated the bios on my Asus P7P55 LX to 1202 from 1003. Data has been copying between drives successfully now for over 20 minutes.

By any chance, are you using a touch pad? If so, changing the touch pad to work as a normal usb mouse will correct issues with a 'unresponsive screen.' Unfortunately, you will not be allowed to use the tap to click feature or scroll using the pad.

Have you tried limiting your open tabs to 4-5? While browsing with different number of tabs open, type free -m at a command line to see how much memory you have list. Manpage for free. More suggestion on checking memory used here.

This looks like your physical RAM is getting full and the system starts to use the Swap. Programmes like Chrome can take easily take up several Gb of RAM. On 12.04, with about 20 tabs open Chromium would get to 2 Gb of RAM in less than a day. You can start by monitoring closely your free RAM with the System Monitor. See if these episodes of high disk usage ...
