** Description changed:
I am able to get an external VGA monitor (or projector) to work if I
start my laptop with it connected. However, if I start the laptop with
it disconnected there is no signal on the external. The Displays screen
shows the external, and thinks that it is active, but there is no signal
being sent to it. This has been a persistent problem since 10.04 (I am
- now on 12.04.... each upgrade hoping something is improved).
-
- I should note that even when it works (starting with display connected),
- Displays still says the monitor is "unknown" (but it sends the signal).
- For the correct resolution to display, I have had to add a few xrandr
- lines for my monitor to my .xprofile file... otherwise resolution is
- limited to default 1024x768. So, resolution issues can be worked around,
- but the main issue is that the external doesn't get a signal without
- starting the machine with it connected.
-
- I have tried:
-
- adding i915.modeset=1 to grub (also i965.modeset=1 since someone posted
- that this helped even though lshw shows i915)
-
- adding following ppa and doing a dist-upgrade: sudo add-apt-repository
- ppa:xorg-edgers/ppa (I have since done a ppa-purge on this ppa so all
- packages have been reverted)
