ATIs own Wiki has a few words on this in regards to 7.12: http://wiki.cchtml.com/index.php/Ubuntu_Gutsy_Installation_Guide#Suspend.2FHibernation_work_with_7.12
Apparently, it works since 7.12 now for all but a few (including my own, grumble) chipsets. quote: Suspend/Hibernation work with 7.12 With Gutsy release, there was a big problem using the ATI proprietary drivers. The Suspend/Hibernate function stopped working. The problem was due to the new SLUB allocator incorporated in 2.6.22 / 2.6.23 Kernel. The problem has been solved in the AMD Catalyst 7.12 driver release. Suspend/hibernate is not working for FireGL 5250. For FireGL 5200, suspend works with the 7.12 fglrx kernel module loaded (which did not work before this release) , but does not work if X is running. For Thinkpad T60 with ATI X1400, to get the laptop to wake up from suspend, I had to change the following in /etc/default/acpi-support: SAVE_VBE_STATE=false POST_VIDEO=false -- [gutsy] fglrx breaks over suspend/resume https://bugs.launchpad.net/bugs/121653 You received this bug notification because you are a member of Ubuntu Bugs, which is the bug contact for Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
