I have a Sony Bravia LCD television, which is now plugged into my laptop using a VGA cable.
I am running an HP Compaq laptop, with a video driver of:
00:02.0 VGA compatible controller: Intel Corporation Mobile 915GM/GMS/910GML Express Graphics Controller (rev 03)
In earlier versions of Ubuntu, it was nearly at the right resolution; in a brand new installation of Ubuntu 11.04, however, it has reverted to a maximum of 1024x768.
Trying to set the resolution using xrandr is giving me annoying error messages, and I read conflicting information about the latest version of Ubuntu not using xorg.conf to set my resolution: is that right?
I'd be grateful for a little bit of help here: in either convincing Ubuntu to recognise the monitor, or to force Ubuntu to change the resolution. Since I'm running this as an external monitor, and the internal LCD screen works perfectly, I'm concerned about breaking the internal LCD support with display reconfiguration as well.
