There is debian box with: --8<---------------cut here---------------start------------->8--- 08:00.0 VGA compatible controller: NVIDIA Corporation G84 [GeForce 8600 GT] (rev a1) --8<---------------cut here---------------end--------------->8--- in it.
I have feeling that graphic drivers have bug, but I am not sure: My simple test: ebook-viewer anthing.epub after some page changes I got: --8<---------------cut here---------------start------------->8--- nouveau: kernel rejected pushbuf: No such file or directory nouveau: ch10: krec 0 pushes 0 bufs 2 relocs 0 nouveau: ch10: buf 00000000 00000002 00000004 00000004 00000000 nouveau: ch10: buf 00000001 00000006 00000004 00000000 00000004 nouveau: kernel rejected pushbuf: No such file or directory nouveau: ch10: krec 0 pushes 0 bufs 2 relocs 0 nouveau: ch10: buf 00000000 00000003 00000004 00000004 00000000 nouveau: ch10: buf 00000001 00000006 00000004 00000000 00000004 zsh: segmentation fault ebook-viewer --8<---------------cut here---------------end--------------->8--- dmesg shows: [245160.258576] nouveau 0000:08:00.0: Xorg[1264]: Unknown handle 0x0000001d [245160.258596] nouveau 0000:08:00.0: Xorg[1264]: validate_init [245160.258598] nouveau 0000:08:00.0: Xorg[1264]: validate: -2 [245162.486435] nouveau 0000:08:00.0: Xorg[1264]: Unknown handle 0x0000001d [245162.486443] nouveau 0000:08:00.0: Xorg[1264]: validate_init [245162.486446] nouveau 0000:08:00.0: Xorg[1264]: validate: -2 [245163.693374] Chrome_InProcGp[137021]: segfault at 8 ip 00007fe615c6bafc sp 00007fe5ceffc1e0 error 4 in libdrm_nouveau.so.2.0.0[7fe615c69000+4000] [245163.693400] Code: b8 02 00 00 00 89 d1 41 56 41 55 49 89 fd 41 54 49 89 f4 55 89 d5 53 89 d3 48 83 ec 28 83 e5 01 4c 8b 37 4c 8b 7f 48 0f 45 e8 <8b> 7e 08 45 8b 46 18 89 e8 83 c8 04 f6 c2 02 0f 45 e8 c1 e9 09 83 The same actions on laptops wiht intel graphics are successful. Any hints if this a bug in xserver-xorg-video-nouveau libdrm-nouveau2 or kernel driver? KJ -- http://wolnelektury.pl/wesprzyj/teraz/ Hindsight is always 20:20. -- Billy Wilder
