A Portal to a Portal

Having had this working ever since I upgraded to Intrepid in early November, I somehow managed to break it on Wednesday whilst trying to get a strange projector combination working. I uninstalled/reinstalled the video drivers a thousand times ( ish ) but couldn't manage to (a) get video working on the internal LCD *and* via an external device and (b) suspend/resume Ubuntu.

However, I think I've cracked it - I went back in time in my blog and found this post from September, where I'd fickered with /etc/default/acpi-support and changed: -

POST_VIDEO=true
# RADEON_LIGHT=true
# DOUBLE_CONSOLE_SWITCH=true
ENABLE_LAPTOP_MODE=false

to: -

POST_VIDEO=false
RADEON_LIGHT=true
DOUBLE_CONSOLE_SWITCH=true
ENABLE_LAPTOP_MODE=true

If it helps, I'm using the fglrx 8.54.3 driver which I got via apt-get install fglrx* - as far as I know, this is not a proprietary driver BUT I MAY BE WRONG.

If it helps, this is how I can see what driver I'm using: -

lsmod | grep -i fglrx

returns: -

fglrx                1813960  32
agpgart                42184  2 fglrx,intel_agp

Having got fglrx installed and having hacked acpi-support, I can now suspend and resume.

I can also switch to a single or dual display ( using my Sharp Aquos 26" LCD display ) using the  ATI Catalyst Control Centre ( command is amdccle ) to switch between screens.

I'll test a real projector later today ....
