Hello. I have a Asus Eee PC 1015PN. I run Ubuntu 10.10, 32 bit. Here is the file DSDT.dsl. I created this file when I used the ION nvidia chip.
On the site https://wiki.ubuntu.com/HardwareSupport/Machines/Netbooks#Asus%20Eee%20PC%201015PN a procedure is described using your ACPI stuff. I have tried this and everything worked fine (reboot, optimus was visible, etc.). I attached also a DSDT_ION+Optimus.dsl file with both graphic cards switched on. However, I couldn't deactivate the nvidia chip at the end via the command echo "\_SB.PCI0.P0P4.DGPU.DOFF" > /proc/acpi/call The system was frozen after 30 seconds. Has somebody an explanation? Thanks in advance. ** Attachment added: "DSDT.dsl" https://bugs.launchpad.net/ubuntu/+source/xorg-server/+bug/312756/+attachment/1815094/+files/DSDT.dsl -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/312756 Title: MASTER: support graphics card hot switch -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
