It seems that it's fixed now. I removed this ppa from sources (/etc/apt/sources.list.d) directory: sudo rm xorg-edgers-ppa-trusty.list.save . Then ran an update and upgrade. Then reboot. Now I can edit the display settings to my heart's desire! Thanks for the help

DO NOT FOLLOW ANY ADVICE TO DELETE COMPIZ! I had the same problem after tweaking compiz. Unfortunately I followed someone's advice to delete compiz and destroyed my installation. The solution I found was to install Ubuntu again. When I chose LVM to look at the layout, it wiped my drive without warning. It is the only option that does not give a warning ...

Hold down the power button to shut down your laptop. press power button again and boot computer back up and login...that should do it. But i will say that laptops like notebooks and chromebooks, are hard to run quality OS's on because their graphic and processing capabilities are low. basically they are smartphones/tablets that look like laptops. So keep ...

Unfortunately I didn't find the thread, but it was something close to Nvidia proprietary driver hangs/freezes/blank screen at login in 13.10 I downloaded the right driver from the Nvidia website, then I removed all the nvidia drivers installed ...

Are you running Firefox? I get freezes when I do too much scrolling around and changing screens rapidly. Also, I found out that if, when it first happens, I can hit AltCtrlDel and leave it for about 5 minutes and the computer logs me out. I just sign back in and start over.

Does it happen when you are browsing in Firefox? I have the same problem as well. It only seems to occur when I am browsing in FireFox and do some rapid moving around of the pages. Also, I installed fresh Ubuntu 14.04 LTS and get a slightly different reaction. Instead of staying frozen until I reboot the computer, if I wait ab out 5 minutes, it goes ...

If you start following random links around the web, it's a good thing if you make a system back-up (you're definitely user type 4) before trying random stuff that ends up freezing your computer. So unless you post an exact list of everything you tried to do, the answer to "Why?" is impossible to answer... Sorry to be the harbinger of bad news. :-(

So after all this time, I think I have - absolutely by accident - found the answer. It looks like the reason for this laggines is glipper. Addon for clipboard in Ubuntu. I have no idea this is the real problem, but all I can say now is that if I terminate glipper, Matlab behaves correctly. Hope it helps someone in the future, as this is obviously a VERY ...

After installing the driver, if it still doesn't work, you can try to disable the dedicated graphic card via the Catalyst Control Center (amdcccle or amdcccle-updates, depending on the driver). In this way you will only use the Intel card integrated in the i3 CPU. This has a couple of side effects. almost surely suspension (and maybe even hybernation) ...

maybe i'm wrong, but i also got my system freezed after a suspend; so i had to hard-Power-off it (On/Off-button pushed > 4s). The only reason i could find was the newly added boot-option at the grub command line: acpi_osi=Linux. After i removed it (plus sudo update-grub2), the suspend / resume behaviour is now ok again. Kubuntu 12.04 (LTS) with ...

The standard Ubuntu NVidia drivers generate some problems on slightly older and slightly newer NVidia hardware. If you want more then the standard Ubuntu repository drivers, install the xorg.edgers PPA. As the xorg.edgers group ask not to give installation instructions directly without linking to their page, this is the best I can do for now... If you ...

This is happening to my Lenovo T510 with Kubuntu 14.10 as well, several times every day. Ctrl+Alt+F1 followed by Ctrl+Alt+F7 "unfreezes" KDE, so no need to reboot for me. It's very annoying, though.

Well so I found the issue; although still don't know if it is hardware or software. The issue was in fact with the Video Card. I swapped the card with another computer and for 2 days now I've had 0 issues. What concerns me is that this card is working fine in Windows 7, and that the freeze was so hard. Everything was shutdown, including networking. ...
