I'm running Natty 64-bit on my Acer TimelineX 3820TG.This notebook has a switchable graphics card (ATI Radeon HD5650 and Intel Chipset).
Currently I am not using the
fglrx drivers. I am a little confused as to how or which way to switch between the cards.
I have downloaded and compiled
ACPI_Call and can load this with the following commands:
sudo insmod acpi_call.ko test_off.sh
This works well for switching to the Intel Chipset and giving me about 7 hours of battery life (very sweet). However, that comes at a cost as I am not able to switch back to the ATI GPU (it causes my system to freeze and the only way to recover is
REISUB), which is required if I want to put the laptop into sleep mode.
I recently read somewhere that
switcheroo was actually made for the ATI/Intel cards so it raised a few questions for me which I hope someone can answer:
- what is the difference between
- What are the advantages/disadvantage of the two solutions?
- How exactly do I use
switcherooon Natty? -- if it's built into the kernel, shouldn't it be automatic?
