Bug ID: 90390
Summary: [NV98] Modesetting causes blank screen because of
INVALID_STATE [UNK0B] chid 1 mthd 0x0080 data
0x00000000
Product: xorg
Version: unspecified
Hardware: x86-64 (AMD64)
OS: Linux (All)
Status: NEW
Severity: normal
Priority: medium
Component: Driver/nouveau
Assignee: [email protected]
Reporter: [email protected]
QA Contact: [email protected]
Environment:
Video card: GeForce 9300M GS (laptop)
Kernel: 4.0.2-gentoo
Steps to reproduce:
1. Boot
2. modprobe drm_kms_heloper
3. modprobe nouveau
Expected result:
Framebuffer initialization
Actually after dozen attempts I had framebuffer initialized once, background
was red, foreground was black and I never was able to achieve this again.
Actual result:
Blank screen. Still able to process keyboard input, so kernel log can be
gathered and system can be safely rebooted.
Results with various parameters:
With `nouveau.noaccel=1` I'm getting black screen instead of blank screen and
system is not responsive to keyboard input.
With `nouveau.modeset=0` nothing happens after `modprobe nouveau`, this makes
me think this is a modesetting issue.
