ubuntu kernel, i915: is there a patch?
I'm right now in a process of encouraging people (mostly people I know, but also others) to use Linux. For this reason I'm trying out various distributions to get a basic idea of which distro to recommend to whom. The other day I installed Ubuntu - a fine distro indeed. One thing happily surprised me, though; I use a Fujitsu-Siemens Lifebook P7010, which has a known problem of losing Direct Rendering after a resume from suspend-to-ram. Under Ubuntu. running the stock kernel, I did not have this problem and I'm guessing the ubuntu devs have written some kind of a kernel patch (though I might be wrong and this has only to do with the xorg drivers). The relevant module is the i915 for the Intel 855GM chipset.
Does anyone have any idea of how Ubuntu handles this? If there's a kernel patch involved, could someone please point me to it and/or any forum discussing it?
Thanks a lot.
