I found that my notebook HP G62 is a Muxless GPU system, with an IGP i915 + DIS Radeon 54xx.
The way I can run an app in accelerated mode is with "DRI_PRIME=1 glxgears" But I cannot enable it by default. Also an important app for me fail to start with this silly message: "intel_do_flush_locked failed: No such file or directory" -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xorg in Ubuntu. https://bugs.launchpad.net/bugs/1406222 Title: Can't switch to Radeon rendering To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xorg/+bug/1406222/+subscriptions _______________________________________________ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp
