[lubuntu] Black screen after login

view full story

http://ubuntuforums.org – Just after the release I installed Lubuntu 12.04 on an old ThinkPad T43 with a 1024x768 resolution display. This T43 is also often used in a dock connected to an old 19" Dell LCD monitor with 1280x1024 native resolution via a standard VGA-cable. Every time the T43 was booted in the dock with the Dell monitor it has been necessary to manually change resolution using the auto setting. Selecting the correct resolution 1280x768 for VGA did not change resolution only the auto setting worked. Yesterday the result of using the auto setting was a black screen instead of the normal desktop. Af (Hardware)
