--- Comment #14 from bruno.n.pag...@gmail.com --- Same issue here (ArchLinux x64, fully updated, Intel 4600HD). I wasn’t able to pinpoint with which package this started, but this might be due to the non-deterministic behaviour of this bug. Here, I’m sometimes able to login right away, sometimes never until reboot. When it fails, I have this in Xorg.0.log : [ 48.872] (EE) intel(0): [DRI2] DRI2SwapComplete: bad drawable [ 48.903] (EE) [ 48.903] (EE) Backtrace: [ 48.904] (EE) 0: /usr/lib/xorg-server/Xorg (OsLookupColor+0x139) [0x598499] [ 48.904] (EE) 1: /usr/lib/libc.so.6 (__restore_rt+0x0) [0x7f9afb8a967f] [ 48.904] (EE) 2: /usr/lib/xorg/modules/drivers/intel_drv.so (_init+0xf413f) [0x7f9af660eaaf] [ 48.904] (EE) 3: /usr/lib/xorg/modules/drivers/intel_drv.so (_init+0xf6727) [0x7f9af6613637] [ 48.905] (EE) 4: /usr/lib/xorg/modules/drivers/intel_drv.so (_init+0x64e60) [0x7f9af64f0380] [ 48.905] (EE) 5: /usr/lib/xorg/modules/drivers/intel_drv.so (_init+0x68b30) [0x7f9af64f7e20] [ 48.905] (EE) 6: /usr/lib/xorg-server/Xorg (WakeupHandler+0xaa) [0x43adca] [ 48.905] (EE) 7: /usr/lib/xorg-server/Xorg (WaitForSomething+0x1ef) [0x590caf] [ 48.905] (EE) 8: /usr/lib/xorg-server/Xorg (SendErrorToClient+0x10e) [0x43609e] [ 48.905] (EE) 9: /usr/lib/xorg-server/Xorg (remove_fs_handlers+0x453) [0x43a293] [ 48.905] (EE) 10: /usr/lib/libc.so.6 (__libc_start_main+0xf0) [0x7f9afb896610] [ 48.905] (EE) 11: /usr/lib/xorg-server/Xorg (_start+0x29) [0x4245c9] [ 48.906] (EE) 12: ?
