Public bug reported: Hello,
I use Kubuntu 14.04.x together with a nvidia graphics card NVC1 (GF108) GT 430 passive and driver nouveau. Standby and resume works with the nouveau driver, but hibernate and resume don't. There is a black screen after resume, then the monitor goes off (no signal) and no keyboard input is possible => Only a hard reset helps. *** Package versions Kubuntu 14.04.1 64bit nouveau version 1.0.11-1-ubuntu2~trusty Mesa 10.3.2, Xserver 1.16.0 (Utopic (14.10) Xstack) kernel 3.16.x (also tested kernel 3.18.5 and 3.19) I have attached the following logs; with kernel parameter nouveau.debug=trace "standby" = "suspend to ram" "hibernate" = "suspend to disk" --- syslog and xorg.log for the working standby syslog_standby_resume.txt standby_resume_Xorg.0.log.old_working.txt --- syslog and xorg.log for the (hibernate) and resume problem syslog_hibernate_resume_NOT_working.txt hibernate_resume_Xorg.0.log.old_NOT_working.txt --- lspci.txt There is a crash at the xserver; [ 101.332] nouveau_exa_upload_to_screen:380 - falling back to memcpy ignores tiling [ 101.348] nouveau_exa_download_from_screen:295 - falling back to memcpy ignores tiling [ 101.348] (EE) [ 101.348] (EE) Backtrace: [ 101.348] (EE) 0: /usr/bin/X (xorg_backtrace+0x48) [0x7fbef984ae18] [ 101.349] (EE) 1: /usr/bin/X (0x7fbef96a6000+0x1a8e59) [0x7fbef984ee59] [ 101.349] (EE) 2: /lib/x86_64-linux-gnu/libc.so.6 (0x7fbef7826000+0x36d40) [0x7fbef785cd40] [ 101.349] (EE) 3: /lib/x86_64-linux-gnu/libc.so.6 (0x7fbef7826000+0x98d66) [0x7fbef78bed66] [ 101.349] (EE) 4: /usr/lib/xorg/modules/libexa.so (0x7fbef334d000+0x5356) [0x7fbef3352356] [ 101.349] (EE) 5: /usr/lib/xorg/modules/libexa.so (0x7fbef334d000+0x57fb) [0x7fbef33527fb] [ 101.349] (EE) 6: /usr/lib/xorg/modules/libexa.so (0x7fbef334d000+0x7e22) [0x7fbef3354e22] [ 101.349] (EE) 7: /usr/lib/xorg/modules/libexa.so (0x7fbef334d000+0x100c2) [0x7fbef335d0c2] [ 101.349] (EE) 8: /usr/lib/xorg/modules/libexa.so (0x7fbef334d000+0x8499) [0x7fbef3355499] [ 101.349] (EE) 9: /usr/bin/X (0x7fbef96a6000+0x131af9) [0x7fbef97d7af9] [ 101.349] (EE) 10: /usr/bin/X (0x7fbef96a6000+0x50281) [0x7fbef96f6281] [ 101.349] (EE) 11: /usr/bin/X (0x7fbef96a6000+0x5339e) [0x7fbef96f939e] [ 101.349] (EE) 12: /usr/bin/X (0x7fbef96a6000+0x571ea) [0x7fbef96fd1ea] [ 101.349] (EE) 13: /lib/x86_64-linux-gnu/libc.so.6 (__libc_start_main+0xf5) [0x7fbef7847ec5] [ 101.349] (EE) 14: /usr/bin/X (0x7fbef96a6000+0x4276e) [0x7fbef96e876e] [ 101.349] (EE) [ 101.349] (EE) Segmentation fault at address 0x0 [ 101.349] (EE) Fatal server error: [ 101.349] (EE) Caught signal 11 (Segmentation fault).
