No video after ubuntu boot up on Thinkpad T21. Problem seems to be intermitten. It will boot up and run normal video after 7 or 8 or more boot ups.
When the problem occurs it goes through the normal Ubuntu splash screen and boot up sequence and then the screen goes blank. It has a blinking cursor in the upper left hand corner - it stops blinking and then - nothing, just a blank screen with no response from keyboard or mouse. .
System will start normally in secure mode. When I get the command prompt and I run "startx" I get a the same blank screen with blinking cursor and then nothing.
System is up and running, I just can't see anything on the screen. Wifi card configures properly (I can see the card lights change when it configures).
Boot up sequence is obviously looking for something to do with the video that does not always "connect"..
You can press "escape" on the thinkpad to bring up the Grub Menu. Don't know if it means anything, but my Grub Menu lists the kernal and then the Rescue Mode 3 times and then memory check. Does not seem to make any difference which one you select to boot.
Any help in resolving the "non start" issue would be greatly appreciated.
