I'm trying to get my new laptop to work with my old tablet - Wacoom PL-550.

Generally, it works, but ubuntu allows only 1 resolution on my system, which it 1920x1080:



xrandr: Failed to get size of gamma for output default
Screen 0: minimum 1920 x 1080, current 1920 x 1080, maximum 1920 x 1080
default connected primary 1920x1080+0+0 0mm x 0mm
1920x1080 0.0*


While this is fine for work, when I try to use it with PL-550, on the tablet the image distortion makes my work hard.

I've tried several tutorials on how to install Nvidia driver on my laptop, but each time I get unbooteable system.

Than I've tried this:



cvt 1024 768 60
# 1024x768 59.92 Hz (CVT 0.79M3) hsync: 47.82 kHz; pclk: 63.50 MHz Modeline "1024x768_60.00" 63.50 1024 1072 1176 1328 768 771 775 798 -hsync +vsync
xrandr --newmode "1024x768_60.00" 63.50 1024 1072 1176 1328 768 771 775 798 -hsync +vsync

xrandr: Configure crtc 0 failed
crtc 0: disable
screen 0: revert
crtc 0: revert


How do I get this to work?
