Windows 7 (host) with VMWare Workstation 11.
Kubuntu 15.04 as Guest.
Problem:
After system startup, in example, on login screen - screen size/resolution is 800x600. Ba, even earlier - during startup when console is active. Making window fullscreen isn't helping, as console output limits itself to small window in the middle.
Setting VMWare window into fullscreen helps a little - screen gets bigger (size of host 1920x1080) - guest Kubuntu applications windows are taking whole screen area. But, for example, desktop wallpaper acts still as if 800x600 was in effect. And inside System settings -> display Virtual screen stays at 800x600, nevertheless Resolution list is long. Unfortunately - 1920x1080 isn't there.
This what xrandr shows:
Screen 0: minimum 1 x 1, current 1920 x 1080, maximum 8192 x 8192
Virtual1 connected primary 1920x1080+0+0 (normal left inverted right x axis y axis) 0mm x 0mm
1920x1080 60.0*+
2560x1600 60.0
1920x1440 60.0
1856x1392 60.0
1792x1344 60.0
1920x1200 59.9
1600x1200 60.0
1680x1050 60.0
1400x1050 60.0
1280x1024 60.0
1440x900 59.9
1280x960 60.0
1360x768 60.0
1280x800 59.8
1152x864 75.0
1280x768 59.9
1024x768 60.0
800x600 60.3
640x480 59.9
From this it seems that proper resolution is set properly.
Now, some magic. I logout from Kubuntu. Login screen is already taking whole 1920x1080 screen area. Settings -> Display shows Virtual screen as 1920x1080, xrandr shows the same set of resolutions. VMWare Tools were installed - at least to the point that I have bidirectional access to shared folders.
What to do to have proper screen resolution right from the beginning? Yea, I know that I can freeze whole session and resume it whenever I need it.
