1) This is a Linux Ubuntu (version 10.04.3) workstation in the Enterprise environment
2) This machines
- getting the IP address from DHCP server
- LAN and internet work well in this machine

3) Problem:

i) My linux machine will periodically "crash" out of the Ubuntu GUI with a message about the screen resolution being set to low ....
ii) Then, I get another box that asks me what I want to do .....
iii) Two of the boxes, I have checked and led me back to the command line, and I have to login again.
iv) One of the boxes, I have checked printed out some status/technical text then either kept churning away or froze, but never gave me back a command line ...


4) I am a windows guy, and I need help from Linux Experts please

5) The GOAL: I often will leave a system running for days as I work on various tasks.

6) How to solve this problem?

7) Thank you

Which GUI are you running, Gnome?
What is the resolution that you are using?
600x480
800x600
1024x768
1280x768
1280x1024?

The setting you have might cause the graphics card to "crash" generate an error.

Hi arnold,

1) """" Which GUI are you running, Gnome?""""
Answer:
- I do not know
- How to check it?

2) """" What is the resolution that you are using?""""
Answer:
- I just do it by default ... (I did not configure anything)
- It is 800x600

3) The things that I will do:
- I will use the GUI
- Go to System > Preferences > Monitor
- I will select the resolution --> 1024x768
- and click APPLY

4) My questions:
- Will it solve the problem? (to achieve the goal: I often will leave a system running for days WITHOUT the above disturbances)

5) Thanks

Ubuntu defaults to the orange ubuntu-desktop, GNOME.

Check whether you have the most current drives for the graphics Adapter that you have installed.

check the contents of /var/log/message to see whether that reports the cause for the failure.
IF you alter the resolution to 1280x1024 if your monitor supports it, see whether that stabilizes.
