Bug #: 44608
Summary: Freeze after Fn-F8 - Next boots: screen remains off
after suspend/resume
Classification: Unclassified
Product: xorg
Version: unspecified
Platform: x86-64 (AMD64)
OS/Version: Linux (All)
Status: NEW
Severity: normal
Priority: medium
Component: Driver/nouveau
AssignedTo: nouveau-PD4FTy7X32lNgt0PjOBp9y5qC8QIuHrW@public.gmane.org
ReportedBy: vincent-fdt-buymaDBGzMOsTnJN9+BGXg@public.gmane.org
QAContact: xorg-team-go0+a7rfsptAfugRpC6u6w@public.gmane.org
On my DELL Latitude E6400 laptop, when I type Fn-F8, the machine almost
completely freezes: the mouse pointer no longer moves, I can no longer connect
to the machine by SSH, and I can no longer control the screen brightness;
however I can still control the keyboard backlight. Once this is done, after
the following reboots, when I suspend the machine with Fn-F1 and resume it, the
screen remains off. I can still connect to the machine by SSH.
To solve this problem, I need to type: "xrandr --output LVDS-1 --auto". Then
the screen-off-after-resume bug no longer occurs... until I type Fn-F8 again.
lspci info: VGA compatible controller: nVidia Corporation G98M [Quadro NVS
160M] (rev a1)
When the resume fails to work correctly, I get the following additional lines
in the logs:
kernel: detected fb_set_par error, error code: -16

The log files are provided in my bug report on the Debian BTS:
http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=655183
Also, I don't know whether this matters, but in the syslog messages, I can see:
Jan 10 01:57:08 xvii kernel: [ 0.171552] [Firmware Bug]: ACPI: BIOS
_OSI(Linux) query ignored
Jan 10 01:57:08 xvii kernel: [ 13.152045] [Firmware Bug]: Duplicate ACPI
video bus devices for the same VGA controller, please try module parameter
"video.allow_duplicates=1"if the current driver doesn't work.
As requested in the Debian BTS, I'll attach drm.debug=6 dmesg.
