Ask Ubuntu is a question and answer site for Ubuntu users and developers. It's 100% free, no registration required.

I recently built a new PC running Ubuntu 12.04 with an Intel Core i5 3450 CPU and am using the built in Intel HD Graphics. Immediately after the installation, I noticed the desktop freezing completely at random times along with the following error message:

The system is running in low graphics mode. Your screen, graphics card, and input device settings could not be detected correctly. You will need to configure these yourself.

I tried troubleshooting this with some of the things I've read here but nothing has worked so far. I've already run a memory test from the GRUB menu and it reported no errors.

Thanks for any help.

I have a similar setup with same intel graphics card and my system is also randomly crashing but I don't see any message. Where are you seeing the error message? I guess you're rebooting after the crash and checking a specific log, which log? –  Paulo J. Matos Jun 27 '12 at 9:42

Try installing the quantal kernel on precise -- The 3.4 kernel has improved support for this hardware -- Quantal is actually shipping 3.5 which includes the support you need. You can follow how to put the new kernel on precise here. Don't worry, if it doesn't work, you always reboot into your current kernel and then uninstall.

Also, take a look at this answer which talks about the timeline for 3.5 kernel on 12.04 and the mainline ppa.

12.04 kernel should work out of the box with Ivy Bridge chipsets. –  leousa Jun 24 '12 at 18:22
