I am a pretty new linux user. So please be as descriptive as possible.
I have Ubuntu 12.04 with Radeon HD 5650 on my laptop. I can easily switch between these two in Windows. I want to be able to switch to Intel HD graphics because AMD causes heating problem and fan runs very noisy. In addition, it is my work computer and i won't be needing any graphics acceleration.
I have a problem with Catalyst driver. When I activate it, I get the error message "running in low graphics mode" on startup. Then I have to switch to the generic driver. I was working on this issue for weeks. I tried many things from the forums but I got nothing. I purged the driver and installed it from AMD website. I caused Linux to crash several times and re-installed it. So that I really don't want to deal with it much. I want to stay on the safe side. So please be sure that it is safe before posting.
sudo su - echo OFF > /sys/kernel/debug/vgaswitcheroo/switch
and I got:
-su: /sys/kernel/debug/vgaswitcheroo/switch: No such file or directory
And there is no option about it in BIOS. What should I do to switch to intel HD graphics?
>>grep -i switcheroo /boot/config-* /boot/config-3.8.0-29-generic:CONFIG_VGA_SWITCHEROO=y /boot/config-3.8.0-31-generic:CONFIG_VGA_SWITCHEROO=y` >>ls -l /sys/kernel/debug/vgaswitcheroo/ ls: cannot access /sys/kernel/debug/vgaswitcheroo/: No such file or directory >>cat /etc/default/grub | grep CMDLINE GRUB_CMDLINE_LINUX_DEFAULT="quiet splash" GRUB_CMDLINE_LINUX=""
When I open Additional Drivers from "System Settings" it says:
No proprietary drivers are in use on this system. ATI/AMD proprietary FGLRX graphics driver (**experimental**beta) This driver is activated but not currently in use.
