For those of us who may not be quite as proficient with Linux - here is
a little more detail (I just struggled through this tonight for about an
hour myself and this bug helped me 80% of the way).
In your /var/log/Xorg.0.log file, look for the following lines:
.
.
(II) GLINT(0): Printing DDC gathered Modelines:
(II) GLINT(0): Modeline "800x600" 40.00 800 840 968 1056 600 601 605 628
+hsync +vsync
(II) GLINT(0): Modeline "800x600" 36.00 800 824 896 1024 600 601 603 625
+hsync +vsync
.
.etc..
Copy all of these "Modelines" entries into the "Monitor" section of your
/etc/X11/xorg.conf file, removing the "(II) GLINT(0): " part. For example, now
the Monitor section of your xorg.conf file may look like this:
Section "Monitor"
Identifier "NEC FE950+"
Option "DPMS"
Modeline "800x600" 40.00 800 840 968 1056 600 601 605 628 +hsync
+vsync
Modeline "800x600" 36.00 800 824 896 1024 600 601 603 625 +hsync
+vsync
.
.etc.
EndSection
However! This still did not work for me. I was not given any other
resolution options after restarting X (and after restarting my machine).
It turns out I had to specify the horizontal sync and vertical refresh
ranges of my monitor as well. This information is also in the
/var/log/Xorg.0.log file. For my monitor, I found these lines:
(II) GLINT(0): Supported additional Video Mode:
(II) GLINT(0): clock: 157.5 MHz Image Size: 356 x 267 mm
(II) GLINT(0): h_active: 1280 h_sync: 1344 h_sync_end 1504 h_blank_end 1728
h_border: 0
(II) GLINT(0): v_active: 1024 v_sync: 1025 v_sync_end 1028 v_blanking: 1072
v_border: 0
(II) GLINT(0): Ranges: V min: 50 V max: 160 Hz, H min: 30 H max: 96 kHz,
PixClock max 240 MHz
(II) GLINT(0): Monitor name: NEC FE950+
I took the "Ranges:" line, found more information about the format of
the xorg.conf file online, and edited my xorg.conf file further. Now
the "Monitor" section of my xorg.conf file looks like this:
Section "Monitor"
Identifier "NEC FE950+"
Option "DPMS"
HorizSync 30-96
VertRefresh 50-160

EndSection
And voila! Restarting X - it came up in 1600x1200 without any blue smoke
coming out of my monitor, and I could select any of the above resolutions.
