Probably after automatic update it cannot sense the correct sttings itself.
I usually resolve this problem by finding the correct monitor parameters manually and putting it into configuration file xorg.conf. So, you have to:
1. find the parameters
launch the terminal and use either
gtf or (better)
cvt utility to get the proper modeline for your monitor. You should get something like this:
Code:
jl@nch-002:~$ gtf 1280 1024 60
# 1280x1024 @ 60.00 Hz (GTF) hsync: 63.60 kHz; pclk: 108.88 MHz
Modeline "1280x1024_60.00" 108.88 1280 1360 1496 1712 1024 1025 1028 1060 -HSync +Vsync
See man gtf for explanation of parameters.
2. insert the parameters to /etc/X11/xorg.conf
(You will need root privileges to edit this file.)
Code:
sudo gedit /etc/X11/xorg.conf
Insert the whole modeline you just got into the "Monitor" section and make sure the name of this modeline ("1280x1024_60.00" in the above example) is included in desired subsection "Display" of section "Screen".
3. restart Xserver
You may search the LinuxQuestions.org to get more information about your problem, it is quite common.
Good luck.
