My problem is sorta the same, except I can't look at the picture so I'm not sure. This is the first time I've had this problem.
I downloaded the Mint 5 KDE .iso, burned it to disk, and put it into my desktop machine. On boot, it progresses to the splash page with the blue thingee which goes back and forth; then fills in the double line progress bar, some starts, and then a crazed screen kind of like a herring-bone zipper pattern. I can dimly see some of the icons but they're doubled and in the wrong places; the screen doesn't respond to the mouse. That's where it stops until I do a hard shutdown. The same DVD booted to live Mint and then installed perfectly in my laptop.
Confusingly, the distros already installed on the desktop, including Mint 4, boot fine, and older CDs/DVDs boot fine to good screens.
The monitor is a Mag Innovision 800V 19'' CRT. The video card is Chrome9 HC IGP (Rev 01). My computer doctor said it looked to him like the monitor is being overdriven. He put his own monitor on, which shows diagnostic mesages. The messages show that his monitor is being driven at 32 khz/ 60hz on startup, but is being driven at 95khz/75hz when the screen goes bad. On older distros which yield good graphics, it goes as high as 75khz/60-70hz. He wondered if Mint 5 weren't maybe optimized for wide form factor flat screens.
I haven't been able to find any way of interrupting the boot sequence to check xorgconfig, etc, or to boot in safe mode.
Any help will be greatly appreciated!
In faith, Dave
