I have a acer TravelMate (Timeline) 8471G with Intel HD4500 and ATI HD4330 switchable Graphics. My Bios-Version is 1.27. I can only change to switchable and discrete graphics in Bios. Ubuntu only works with the "discrete" option where the ATI graphics card is on. (01:00.0 VGA compatible controller: ATI Technologies Inc M92 LP [Mobility Radeon HD 4300 Series])
I have attached my DSDT.dat ** Attachment added: "DSDT.dat" http://launchpadlibrarian.net/48460667/DSDT.dat -- support graphics card hot switch https://bugs.launchpad.net/bugs/312756 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
