View Full Version : [all variants] Dell BIOS screen screws up X screen

August 3rd, 2009, 10:04 PM
How can I switch the screen resolution (or refresh settings from within a running xserver) using shurtcut keys?
The problem behind:

My Lattitude detects a non 90W power supply when I use the car adapter, displays a full screen text message saying that it will switch to battery optimized mode together with the famous <hit any key to continue>. Afterwards the screen is screwed up, the bars that reside by defaut on top and buttom of the screen appear displayed horicontal in center of the lcd and pixel are stretched by about 2 times (so only the left half is visible; mouse moves still need to be placed in their normal position --> almost impossible to hit the right place to switch screen resolution back using the mouse...)
