Поменял файл /etc/rc.local
915resolution 4d 1920 1440
exit 0
Подрихтовал xorg.conf
Section "Screen"
Identifier "Default Screen"
Device "Intel Corporation Mobile 945GM/GMS, 943/940GML Express Integrated Graphics Controller"

DefaultDepth 16
SubSection "Display"
Modes "1920x1440"

Поменял /etc/default/915resolution
MODE=4d
XRESO=1920
YRESO=1440
BIT=16
А разрешение все равно 1280x800
Хоть тресни.
P.S. Пытался поменять на 1600x1200 - та же история
