** Description changed:
I started to have problem with external display after I upgraded kernel
to 2.6.38-11-generic-pae.
When I call xrandr to reconfigure my displays, HDMI monitor goes to
standby on my DELL E6120 laptop.
It has following display adapter:
--
00:02.0 VGA compatible controller: Intel Corporation 2nd Generation Core
Processor Family Integrated Graphics Controller (rev 09) (prog-if 00 [VGA
controller])
Subsystem: Dell Device 0493
Flags: bus master, fast devsel, latency 0, IRQ 42
Memory at e140 (64-bit, non-prefetchable) [size=4M]
Memory at d000 (64-bit, prefetchable) [size=256M]
I/O ports at 4000 [size=64]
Expansion ROM at unassigned [disabled]
Capabilities: access denied
Kernel driver in use: i915
Kernel modules: i915
Step leading to the problem:
1. Boot laptop normally with HDMI monitor connected - HDMI monitor goes on
2. Login to the Gnome - HDMI monitor is still on
3. Now I try to switch primary display to hdmi monitor with xrandr:
xrandr --output HDMI1 --left-of LVDS1 --auto --primary
With older kernels everything goes fine.
But with 2.6.38-11-generic-pae it shuts monitor...
It goes to standby mode and says that no signal...
