Ubuntu message: Video mode not supported, ends session


Ubuntu 7.04 (with its enhancements over the year) had been working ok till the new Yahoo mail kept repeating that the screen resolution had to be 1024x768.

No amount of editing the file in the directory X11 made any difference.
Next I looked up other solutions. Unfortunately the first one I tried on the command line, the command is forgotten, shut the system in a jiffy with a blank screen.

Reinstalling Ubuntu begins to start but then suddenly a message floats about the screen: Video mode not supported. I seem to have lost all the fancy stuff I had adorned the Desktop with.

Any workable cure would be appreciated with thanks.

Does your screen support 1024x768?

Exclamation fix for Video Mode Not Supported

I had the same problem and thought I had tried everything, but naturally the last one was the one that worked. My CPU had been installed on my motherboard and tested by the shop I bought it from, so I assumed they had done it right, but what I found after pulling all the drives out of the case to get at the motherboard and memory was that they had set the jumpers (there were a lot!) to SDRAM instead of DDR, so I had to change them. And that did it! No more problems and the 3 volts instead of 2.5 volts did not seem to have hurt my 1.0 GB of memory, as far as I can tell.
