view story

https://bbs.archlinux.org – Here's an interesting observation.My setup is the following: notebook computer + external display. 2 user accounts A and B and I'm using GNOME 3.4 in fall-back mode.I think it's important to know, account A was created before I bought external display and started using it as a main one. Account B was created when I already used external display.So, I use only external display at 1920x1200 resolution:xrandr Screen 0: minimum 320 x 200, current 1920 x 1200, maximum 8192 x 8192VGA-0 connected 1920x1200+0+0 (normal left inverted right x axis y axis) 518mm x 324mm   1920x12 (HowTos)
