---------- Forwarded message ---------- From: BajK <[email protected]> Date: 2010/12/27 Subject: Acer Aspire 3820 TG To: olibob <[email protected]> Good day, I recently bought an Acer Aspire TimelineX 3820TG and I love it and now I am glad that I have found this launchpad group. Since I do not like Windows and the first thing I did was installing Kubuntu on that machine which runs fine, I now have some kind of convincing a friend of mine that hybrid graphics is possible. I am currently writing a couple of scripts which enable me to switch from the Intel graphics to the powerful ATI and vice versa. It is kind of promising. There are still a few flaws, though. At first, I hate ATI- driver developers (fglrx, the open source one is fine of course) because they make my life so hard. In order to make the switch a success, I ALWAYS need to purge and/or re-install fglrx, otherwise it falls back to the Vesa driver although I blacklist fglrx when starting with the Intel graphics. Another more severe problem is that I need to do a restart and then change a setting in the BIOS. There is a “Graphics mode” switch which can be either set to “discrete” (the ATI graphics enabled only) or “switchable”. I have a kernel module timelinex_acpi found somewhere in the ubuntu forums which disables the ATI graphics. But I cannot re- enable it unless I set the graphics mode to “discrete” which forces the ATI graphics on. But even when I already had the ATI graphics on and I switch back to “Switchable” I end up with the Intel graphics only. What I need is the opposite of the kernel module which ENABLES the graphics card. If I have this, then it shouldn‘t be that much of a problem switching the graphics cards on the fly, i.e. load and unload the neccessary kernel modules, re-write x config and restart the X server. But without it, I always need to go to the BIOS and switch things manually.
