Here's yet another set of data to add to the bug: I fall into the category of people experiencing regular desktop freezes (every few minutes) but mouse can still be moved and I am still able to switch to a TTY console. However, I am currently using Linux Mint 13 (so not Unity based, but very closely derived from Ubuntu 12.04) on Intel Sandy Bridge (quad core i7-2720QM), integrated graphics and nVidia Corporation GF108 [Quadro NVS 4200M], and I am *not* using the proprietary Nvidia drivers.
There does not seem to be anything in the logs (syslog, kern.log, nor X logs) that provides any hints as to what's going on. I was previously running Ubuntu 11.10 and Linux Mint 12 with no problems and with both ASPM and RC6 enabled (i915.i915_enable_rc6=1 and pcie_aspm=force), so it is less likely that the ASPM/RC6 related changes in Ubuntu 12.04 kernels could be the cause. Perhaps people using Ivy Bridge get a hard freeze, but people using Sandy Bridge get just an X freeze? I can help debug this if anyone from Canonical is interested. I can grab stacktraces, strace, etc if needed, just need to know which processes to look at. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/993187 Title: ubuntu 12.04 completely freezes frequently To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xorg/+bug/993187/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
