Title:
Dead screen on resume from suspend Dell Insp. 9200
Status in “linux” package in Ubuntu:
Expired
Bug description:
Preface: I was directed to report this as a bug against xorg;
apologies in advance if it's filed against the wrong package.
One of my machines is an old Dell Inspiron 9200 laptop. Contained
therein is an Intel chipset and ATI Mobility Radeon 9600 graphics
device. I am running Ubuntu 12.04 "Precise", from fresh install from
earlier today. This machine has the latest Gallium3d drivers
installed from a PPA ( https://launchpad.net/~oibaf/+archive/graphics-
drivers/ -- it is a stripped down set of just video drivers and
necessary related libraries, so I don't have to mess with the full
xorg-edgers or -swat repositories ).
Please note that this problem also exists with the default open-source
Radeon driver supplied with Precise.
I do NOT use the proprietary driver blob, (it no longer supports this
machine).
When I suspend the laptop, it goes down just like it should. However,
when I resume it, it wakes up but the screen remains turned off. That
is, it appears completely dead to the observer - not even the
backlight comes on - but I can ssh in from another computer, execute
commands, reboot, whatever I want as long as it doesn't require me to
look at the laptop's screen.
While attempting to come up with a workaround, I ran across the
vbetool command, namely "vbetool post". When executed as root (via
ssh), it resets and wakes up the laptop's video device, but whether
the laptop is focused on the X display or on a virtual console, the
screen is garbled. Whatever is supposed to be there IS in fact there,
it's just twisted and distorted beyond usability. The only exception
is that the mouse pointer is *mostly* intact (slightly distorted). I
can move said pointer around like usual, and could possibly even click
on stuff, log into the display manager, etc., but of course I still
can't see what I'm doing.
Switching to another virtual console (e.g. Ctrl-Alt-F1 or 'sudo chvt
1') and back to the X display has no effect - if it was dead, it's
still dead. If it was garbled from having tried 'vbetool post', it
remains garbled (but the contents change).
Further, if I disable Kernel Mode Setting with the "nomodeset" boot
parameter, I am then able to suspend and resume to my heart's
content..... Except then the video driver gets downshifted to the old
VESA one, as Gallium requires KMS. If KMS is disabled, I can also use
the old Radeon driver, but then I lose 3D/OpenGL acceleration, so at
that point I may as well have been using VESA.
I also tested, briefly, this machine's ability to run Intrepid Ibex
using the proprietary ATI blob (v9.3) - suspend, resume, 3D
acceleration all worked as expected in that configuration, but of
course that version of Ubuntu is quite out of date and unsupported, so
it got overwritten with Precise.
I am currently operating on that fresh re-install. Every partition on
the machine was re-formatted prior to the install, leaving nothing
behind from any previous OS.
Only a minimal amount of additional software has been installed since
that time. None of the system's configuration files have been altered
except for the grub config (when I attempted unsuccessfully to disable
KMS).
What I expected to happen, of course, is that the laptop should turn
on and re-initialize the screen when it comes up from suspend without
me having to run stuff like vbetool, which doesn't work for me anyway.
