Correction: Machine is Lenovo W520 with Nvidia/Intel graphics (not T520, don't know why I mistyped that)
I am in the closing stages of a large project with a serious deadline. I will not be able to reinstall things until the end of September. I'm really sorry. In this case it would entail switching from Kubuntu to Ubuntu, redo my whole dev-setup and work with it for a several days to make sure the issue was gone. I can however test the kernels, and when my project is over I will be happy to participate in more extensive testing - also future bugs. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1213022 Title: Detected a hung GPU, disabling acceleration. Status in “linux” package in Ubuntu: Incomplete Bug description: Kubuntu 13.04 Thinkpad T520 Bios: automatic (i.e. detect support for descrete graphics, though does not seem to detect anything) $uname -a Linux fk1304 3.8.0-27-generic #40-Ubuntu SMP Tue Jul 9 00:17:05 UTC 2013 x86_64 x86_64 x86_64 GNU/Linux Screen will regularly (typically 1-3 times a day) freeze for a few moments, then the acceleration is disabled. I have seen this happen in different situations: When switching between folders in dolphin When scrolling in FF When switching between desktops (I use kwin set up with a 9 desktops grid, no Compiz) When running a java app and a vmware virtual machine I have not found a certain way to make this happen, though it seems to be related to spikes of heavy activity.
