[Bug 205049] garbled graphics
https://bugzilla.kernel.org/show_bug.cgi?id=205049 --- Comment #17 from Pierre-Eric Pelloux-Prayer (pierre-eric.pelloux-pra...@amd.com) --- This bug has been fixed in Mesa, but is not part of a release yet. So the 3 possible fixes are: - compile Mesa from git - or find a package for your distribution that contains Mesa git - or define this environment variable system-wide "AMD_DEBUG=nodcc" until Mesa 20 is released and your distribution is updated. -- You are receiving this mail because: You are watching the assignee of the bug. ___ dri-devel mailing list dri-devel@lists.freedesktop.org https://lists.freedesktop.org/mailman/listinfo/dri-devel

It just seems to contain a heap of forum comments, but no nothing "useful" in the conventional sense where a user can download and install a damned fix. -- You are receiving this mail because: You are watching the assignee of the bug. ___ dri-devel mailing list dri-devel@lists.freedesktop.org https://lists.freedesktop.org/mailman/listinfo/dri-devel

https://bugzilla.kernel.org/show_bug.cgi?id=205049 --- Comment #12 from le...@onet.pl --- Is anyone actually working on this problem? I just upgraded from Fedora 30 to 31, hoping that the upgrade might include other miscellaneous changes that fix the problem, but the problem is EXACTLY THE SAME. Nothing has changed. I'm starting to lose my mind with this chronic lack of progress. Support for the Lenovo Ideapad 330 has been been severely broken for at least the last 6-7 kernel versions!

https://bugzilla.kernel.org/show_bug.cgi?id=205049 --- Comment #9 from le...@onet.pl --- Kernel 5.2.18 has the same problem. What's going on? I've already increased the default number of old kernels that are kept by grub, from 3 to 5, but at this rate, I'm going to have to either increase it again, or stop updating. The last 'usable' kernel (version 5.1.20-200) has other problems too, including unexplained freezing once or twice a day, and wifi that 'sometimes' stops working after resuming from sleep. These are all regressions from years ago. -- You are receiving this mail because: You are watching the assignee of the bug. ___ dri-devel mailing list dri-devel@lists.freedesktop.org https://lists.freedesktop.org/mailman/listinfo/dri-devel

https://bugzilla.kernel.org/show_bug.cgi?id=205049 --- Comment #5 from le...@onet.pl --- Ok, this is what I've tried: holding shift to force the boot menu to show up, then pressing e to edit the options for kernel version 5.2.17, then appending amdgpu.ppfeaturemask=0x3fff, and finally pressing Ctrl-x. If I add a space and put the text at the end of the last line with text already on it, the error appears for a few seconds, then the Lenovo splash screen appears indefinitely and nothing else happens until I cycle the power. On the other hand, if I put the text on a new line, there's no error message and Fedora boots normally, but the graphics issues persist. I tried a total of 6 different boot edits with amdgpu.ppfeaturemask=0x3fff, amdgpu.ppfeaturemask=0xfffdbfff, and amdgpu.ppfeaturemask=0xfffd3fff, with the same result each time. -- You are receiving this mail because: You are watching the assignee of the bug. ___ dri-devel mailing list dri-devel@lists.freedesktop.org https://lists.freedesktop.org/mailman/listinfo/dri-devel
