Forcing a Higher Resolution on the Zotac Workstations
Source: http://superuser.com/questions/311378/how-to-get-a-higher-resolution-on-ubuntu-11-04-using-an-intel-chipset
You can try setting your resolution to the desired level manually.
First, run this command, changing the example 1920x1080 resolution to the resolution you want:
cvt 1920 1080
That will spew out something like this:
# 1920x1080 59.96 Hz (CVT 2.07M9) hsync: 67.16 kHz; pclk: 173.00 MHz
Modeline "1920x1080_60.00" 173.00 1920 2048 2248 2576 1080 1083 1088 1120 -hsync +vsync
We're only interested in the chunk after the quotes and before the -hsync, e.g.
173.00 1920 2048 2248 2576 1080 1083 1088 1120
Use that in the next command to add a graphics mode:
xrandr --newmode clever_name 173.00 1920 2048 2248 2576 1080 1083 1088 1120
Now, add your new mode to your VGA output:
xrandr --addmode VGA1 clever_name
Finally, switch your VGA monitor to use it:
xrandr --output VGA1 --mode clever_name
Now that that works, you can make it take effect every time you log in. To do so, create the following files somewhere:
fix-resolution.sh with what is called a shebang line and then the last three commands you ran that got it working before, e.g.:
#!/bin/sh
xrandr --newmode clever_name 173.00 1920 2048 2248 2576 1080 1083 1088 1120
xrandr --addmode VGA1 clever_name
xrandr --output VGA1 --mode clever_name
fix-resolution.desktop with the following contents:
[Desktop Entry]
Name=fix resolution
Exec=/usr/bin/local/fix-resolution.sh
Now, copy the files to the appropriate places on your hard drive and make the script executable. From a terminal:
cp fix-resolution.sh /usr/local/bin
chmod +x /usr/local/bin/fix-resolution.sh
cp fix-resolution.desktop /etc/xdg/autostart
This will run the commands that force your monitor to the proper resolution every time someone logs into your computer.
