Unfortunately I do not have this machine any longer so I cannot help with more information regarding this issue.

I have a HP Compaq 8510p laptop with a Radeon HD 2600 GFX card. I've connected an extra screen (HP 19" - max resolution 1280x1024x60hz). Now, the dualscreen setup has been working flawlessly, until one of the fixes upgraded the kernel. Anything after 2.6.32-10-generic has been causing HSYNC problems on the extra screen. It looks like every other horizontally line is at least 1 pixel off horizontally, and this pattern scrolls downward, making the dual screen impossible to use. When I boot with grub, kernels <= 2.6.32-10-generic works perfect. Anything above causes this behaviour. Not only in X but also using the console (which per default seems to run some VESA graphics resolution), which leads me to believe there is something awry with the radeon kernel module or similar. I've checked /boot/grub/grub.cfg, but there is no difference between the boot entries. I hope the source of this can be found & fixed as I cannot go above any kernel revision >2.6.32-10-generic until it's fixed. Mainline kernel 2.6.34-999-generic #201004211003 works as normal.
