This is kind of dumb, but I think the reason it seemed like the graphics glitches were gone with 8.10 is because the basic problem here is that video memory is not being refreshed during sleep. RAM state will generally degrade over time, reaching a random state after a minute or so (but not instantly). So of course, when I was regressing this bug, I slept the laptop for short periods of time, keeping the ram in a closer-to-correct state.
It's pretty clear that video textures just have to be reloaded on resume. The graphics glitches are all compiz-related, and look like 3d texture corruption. -- Graphics glitches coming out of suspend with Radeon 9700 https://bugs.launchpad.net/bugs/155116 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
