Weird screen on old IBM Thinkpad
I installed Ubuntu 10.04 last night and it seemed to install OK but when it finally booted up the screen is split into 3 sections "vertically". The 2 on the right side are identical purplish and the left side is a gray color. NO icons on top but do have a pair of shutdown buttons and 2 trash cans, one in each pane on the right. The mouse will move into all 3 screens but dissapears when crossing over the vertical lines. Once in a while a window will pop up behind all this mess. You can see something to click on but what is anyones guess.
This is a fairly old IBM Think pad. 900mhz with 512m ram. I wanted to use it to run cnc out the parallel port. Newer laptops do not have parallel ports. Not sure of the date of manufacture but near 2001 I believe. I think the 512m ram is about all it can handle so that is not a option. Please let me know if the Think Pad is to weak to handle Linux Lucid. I understand Lucid is about the only one that can run the CNC program??
To add further, when Linux boots up there is a nice purple screen with Ubuntu and the 4-5 dots blinking in sequence. After that is when the screen goes wacko. I can only think it is not enough video to load properly.
The computer worked OK with Windows XP, what am I doing wrong? I just thought I would try Linux and see how well the CNC program works on that. Thanks in advance for any help anyone can give.
