vgaswitcheroo seems to need more fine tuning.

Well, I was impressed by the PowerXpress (Crossfire technology) that will save battery life and hours.

as searched over the internet, the vgaswitcheroo/switch did not solve many of these problems... like turning off the discrete card in PowerXpress mode.

so Installed the ATI vendor driver on SUSE and it seemed to work fine till now. But still turning off the disceret card doesn't increase the battery remaining time since both the internal and discreet cards are on..

Keeping fingers crossed for this thing to happen..

Ciao..

Installing Suse 11.4 / Ubuntu 10.10 ATI Radeon HD6370 propriatary driver on hp dm4t

Well, I tried the Xorg (OSS) version of the driver (radeonhd) and looks like the support for this specific card is not available..

Hence, I tried installing the vendor driver the AMD ATI Catalyst for Linux.

well, before that, we have to uninstall radeonhd (SUSE : YAST->Software management) which is installed by default when the OS is installed..

now download this

http://www2.ati.com/drivers/linux/ati-driver-installer-11-2-x86.x86_64.run

do the following

chmod +x /temp/ati-driver-installer-11-2-x86.x86_64.run

sh ./temp/ati-driver-installer-11-2-x86.x86_64.run

choose auto discovery option then shutdown -r now

you should have the display driver installed and all the 3D effect you wanted.

I must say, the rendering performance is much slower than the radeonHD opensource version, but radeonHD driver has some driver load issues when booted without the nomodeset option due to the recent switch to DKMS route chosen by the Linux community...

As always, open source developers will find a way out for this.
