Mihaly, what version of ubuntu are you using? Could you please post the results for:
$ lsb_release -a and $ apt-cache policy xserver-xorg-core I'm marking this bug report as invalid, since this is a known issue for Alpha 2, and cannot yet be fixed. See http://www.ubuntu.com/testing/jaunty/alpha2 "A new XServer, version 1.6, is included in Alpha-2. The binary proprietary drivers -fglrx and -nvidia are not yet supported for this server and will exhibit various serious issues if run against it. Users of these drivers are encouraged to wait or to switch to the corresponding open source drivers (-ati and -nv respectively) in the meantime. 308410" ** Changed in: mesa (Ubuntu) Status: Confirmed => Invalid ** Changed in: xorg (Ubuntu) Sourcepackagename: mesa => xorg -- glxinfo badRequest (invalid request code or no such operation) https://bugs.launchpad.net/bugs/293012 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
