I now have a definitve answer. I found the "Maintanance and Service Guide" for my laptop. It reads: "32 MB of discrete video memory".
At least it shows, that lspci does not report the actual video memory, and if the Xorg log doesn't report it either, answering this question is non trivial. The bug description remains valid. -- (32MB) certain windows drawn garbled when XAA is used https://bugs.launchpad.net/bugs/426582 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
