LinuxMint 10 KDE problems *Possibly regarding Graphics Card*
 

Well, I downloaded Linux Mint 10 KDE VIA Torrent, but there was nothing wrong with the ISO file, it worked perfectly in Virtual Machine... but there's a problem with it running now. Well, let's say I have a page open, and the page changes *Not web browser, but an App's page* parts of the previous page remain there until after I move or resize the program. Please do not tell me that this is the way Linux Mint is supposed to be... Someone told me that everything else is fine, 3.2GHz Dualcore *4 CPUs*, 1TB HDD, and 6GB of RAM, but I have Intel HD Graphics and I've had MANY problems with it when I'm playing games, some games I can't even run at the lowest quality... I wouldn't have thought that Linux Mint would have required a good Graphics card, I might have reconsidered... but if you someone were to tell me a way to fix my problem... perhaps by modifying certain features? Any help?

You could try booting with the nomodeset option to see if kernel mode setting for your intel graphics is causing the problem.
To boot with nomodeset, when the grub2 menu comes up, hit the "e" key to edit the Ubuntu boot entry. Scroll down to the linux line with the arrow keys. Then move the cursor to the end of the line. Replace the words quiet and splash with nomodeset. Then hit ctrl + x to boot Ubuntu.
This will not make any permanent changes to the way your computer boots. It only affects the current boot.
If booting with nomodeset helps, then you can edit the /etc/default/grub file and add nomodeset in between the quotes to the end of the GRUB_CMDLINE_LINUX="" line. Then run to update the /boot/grub/grub.cfg file. This will enable the nomodeset option every time that Ubuntu boots. See this tutorial for reference: https://help.ubuntu.com/community/Gr...b%20%28file%29
The intel graphics cards are not very good for playing 3D games.
You could try disabling all desktop effects if you currently have them enabled. This may improve graphics performance a bit.

Also, doing a real install of Ubuntu, instead of using a virtual machine, may give you slightly better performance.
If this computer is a desktop, and you really want good graphics performance for 3D games, it would be worthwhile to install a decent nvidia graphics card. With your specs, the intel graphics card is definitely the limiting factor on your computer's performance.

Not sure if this is related (I don't use KDE), but I've seen similar problems when running xcompmgr with openbox. Switching window managers to metacity (and enabling compositing) eliminated the problem. I've got onboard Nvidia Geforce 9100 graphics and am using the nouveau driver.
