the kernel log
When Linux resumes after suspension to RAM, I get no display until next
boot, but the backlight is on. I think this was true since I started
using this distro, but I rarely tried to use suspend.
This happens invariantly to Xorg.
Although my hardware is 64-bit, I use a 32-bit Linux.
Software versions:
* Linux 3.16.1
* libdrm 2.4.56
* mesa 10.2.6
* xf86-video-nouveau 1.0.10
nouveau reports errors like these to kernel log when the display should
turn back on:
