*** This bug is a duplicate of bug 1735594 *** https://bugs.launchpad.net/bugs/1735594
This bug, or what I believe to be this bug and not 1735594, cropped up for me in an update on July 24, 2018 to kernel 4.4.0-131. Have spent the last week + searching the web and residing trying to figure things out and have landed here. I am running Ubuntu 16.04 LTS on an old Acer Extensa 4420 with AMDS TK-57 processor and on board Nvidia 1250 video. System boots into login screen just fine, but any attempt to Login, either Gnome or Ubuntu gets me to a wallpaper only with a mouse cursor. Messages flash up on the screen but do not stay long enough for me to interact with them. Initially one of the said Compiz crashed, but after the first reboot (holding the power switch down), that message no longer appears. I can boot into Grub and duplicate issue with any of the 7 older kernels I have. Can drop to system prompt from GRUB but am too inexperience to know what to do then. This is being posted form another computer running Windows as laptop is currently unusable, and after many years of reliable Ubuntu service. Please help. -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to mesa in Ubuntu. https://bugs.launchpad.net/bugs/1741447 Title: Unity / Compiz in a crash loop after login, after mesa updates of 2018-01-04 Status in Mesa: New Status in mesa package in Ubuntu: Confirmed Status in mesa source package in Xenial: Confirmed Status in mesa source package in Artful: Confirmed Bug description: GUI is constantly crashing, can't start desktop Jan 5 11:21:29 1810 kernel: [ 806.368754] compiz[10824]: segfault at 0 ip 00007f83c4f31c16 sp 00007ffd48dfc2f0 error 4 in i965_dri.so[7f83c4954000+82d000] Jan 5 11:21:40 1810 kernel: [ 817.279740] compiz[11111]: segfault at 0 ip 00007fda21519c16 sp 00007ffd7b40a150 error 4 in i965_dri.so[7fda20f3c000+82d000] Jan 5 11:22:30 1810 kernel: [ 867.445137] compiz[11271]: segfault at 0 ip 00007f8462855c16 sp 00007fff07c857f0 error 4 in i965_dri.so[7f8462278000+82d000] Jan 5 11:22:46 1810 kernel: [ 883.319195] compiz[11458]: segfault at 0 ip 00007f72b7af0c16 sp 00007ffc3b92d830 error 4 in i965_dri.so[7f72b7513000+82d000] Jan 5 11:23:01 1810 kernel: [ 898.587610] compiz[11516]: segfault at 0 ip 00007fe25113dc16 sp 00007ffcf79754c0 error 4 in i965_dri.so[7fe250b60000+82d000] In /var/crash: _usr_bin_compiz.999.crash Did manage to start a GUI in Low graphics mode (lowgfx.conf) but this is not really usable. - dash not working - no window switching - sometimes all windows disappear for a few seconds So effectively my laptop is not usable after latest updates.
