I have a ThinkPad W500 with switchable graphics, that is, with two graphic chips: - ATI FireGL V5700 [mostly the same as Radeon 3650] - Intel GMA 4500MHD
In the BIOS you can select whether it should enable only one of them and which, or activate both and let the OS switch them on and off. Since AFAIK Linux doesn't support the switching, I enable only one of them at a time. I have this problem with both chips, using the Free drivers. I have no custom kernel or driver or anything like that. Before upgrading to 10.11 from 10.04, I had the Gnome desktop running with Compiz, with no problem. The only way to get a working desktop now is to select Unity-2D which works fine. Trying to dianose it I ran glxinfo, but it hung up: just like when starting Unity, it did nothing for a few seconds before giving the error message. Before posting this comment I just tried glxinfo again, and it now works fine. I updated everything yesterday. I'm sending this message for the record and re-login choosing Unity to see if it works. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/832681 Title: Unity fails to start with ATI proprietary drivers - GL_ARB_vertex_buffer_object not supported To manage notifications about this bug go to: https://bugs.launchpad.net/fglrx/+bug/832681/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
