Sorry, I switched up some terminals and accidentially sent the
xorg resolution file from my other computer, the actual file would
be:
# cat /etc/X11/xorg.conf.d/10-monitor.conf
Section "Monitor"
Identifier "VGA-0"
Modeline "1280x960" 122.24 1280 1328 1424 1696 960 961 964 1002
+hsync +vsync
Modeline "1152x864" 112.44 1152 1216 1344 1560 864 865 868 906
+hsync +vsync
Modeline "1024x768" 99.19 1024 1072 1168 1376 768 769 772 810
+hsync +vsync
Modeline "800x600" 77.84 800 816 896 1080 600 601 604 642
+hsync +vsync
Modeline "640x480" 62.27 640 656 720 864 480 481 484 522 +hsync
+vsync
EndSection
Sorry for mixing that up, and sorry for the previous message being
HTML-formatted, I forgot to check text only
regards,
Maite
