Integrated graphics seems to be the problem: this takes some of the main RAM memory and this somehow causes the problem. This seems to be confirmed by what Kai Nickel reports. After putting an old Nvidia card in his system the problem is gone. This is most surely a card that does not share memory but has it's own dedicated memory. Kai, can you confirm this?
The problem than still is, were exactly the bug is situated. Many (but not all) seem to find a (partial) solution by installing a newer kernel, others seem to find a solution with a different Nvidia driver (of course the latter only applies to those using Nvidia cards). However this is still a very serious problem as all newer low and mid end desktops and laptops come with integrated graphics these days. It is very hard to believe that no one at Canonical noticed this bug until now. Bug still unassigned. Bug heat already 560: more than twice the number of a security related bug, yet no one seems to bother. Weird, and of course not very healthy for Ubuntu. @ Yurx Cherio: I share you thoughts. Let us know if kernel 3.4 brought the solution for you. I have an acer 7520 laptop with 2 Gig of Ram, Geforce 8400M with AMD Turion64 X2: an older system, but until version 12.04 without (serious) problems. For my installing a newer kernel did not solve the problem: my system became a bit more stable, but still not workable, still hanging at least once an hour. Before installing a newer kernel after 10 minutes the show was over! Now back with 11.10 and waiting for a solution before upgrading. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/993187 Title: ubuntu 12.04 completely freezes frequently To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xorg/+bug/993187/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
