[Bug 312756] Re: support graphics card hot switch
I have a Acer timeline 4810tzg-413g32mn. This laptop has a Intel and ATI GPU card.
I have a dual boot with Windows 7 and Ubuntu 9.04. On Windows 7 the laptop runs cool and the fan runs about 10% of the time. The battery time is 5 hours or so.
On Ubuntu the Laptop is hotter and the fan runs all the time, because
both GPU's are running. The battery lives for 2 hours or so. :(
I don't know exactly Witch output I must place here so I copy past
everything. Here, and hope I can help you.
Here go's nothing...
