I have HP ProBook 4310s loaded with Linux Mint 7 Gloria (Jaunty 9.04) with all the latest updates and ATI Proprietary driver (for ATI Mobility Radeon 4330).
I can't identify the culprit of the leak or is it just the physical memory can't be cleared correctly.
Below is the screenshot after 3 hours of use, 1.4gb physical ram is used which doesn't tally with the sum of all processes' memory. It kept on growing over time. http://imagebin.ca/view/JJG29khE.html
I have tried server and generic kernel 126.96.36.199 with xorg-server-no-backfill (and stock xorg-server as well), both to no avail.
I hope you can shed some light on this weird issue.
If further information is required, i will gladly supply.
Thank you very much,
