Hi All, I've setup ubuntu gutsy with the amd64 kernel on my MBP 2,2 running the radeonhd driver and so far its pretty usable. I wouldn't say the radeonhd driver is blazingly fast but its okay and power consumption is pretty low (21-23 watts). I am thinking about trying fglrx but I have some overall requests/questions first. First, does anyone have a finely honed touchpad section from their xorg.conf file that they would be willing to share. Since this is pretty machine specific I guess it would have to be another MBP 2,2 owner. Right now I have 1, 2, and 3 finger tapping enabled and I also have two finger scroll enabled. Two finger scroll actually works relatively well but overall I find the mouse a bit jittery and also far too sensitive to singe-finger tapping. I'm constantly accidentally clicking things I don't want to. In my previous install (which I've wiped) two finger scrolling didn't work well but mouse movement and tapping was better. Now its the other way round. I hope that its possible to somehow balance the two and hopefully someone has already done it and can save me some time. The other things is that I might try to install fglrx. If I do so I guess I will be restricted to 2.6.22 (which is what I'm running now) which means no NO_HZ option because that's only supported on 2.6.23 in 64-bit right? I suppose I'll just have to wait if I want acceleration and NO_HZ. Powertop seems to suggest I really should be running NO_HZ -- do people see a lot of improvement from this? The other reason I'm worried about switching to fglrx is suspend to ram. Right now that seems to work (at least the 2-3 times I tried it). I recall people saying that its broken with fglrx. Is this just a SLUB to SLAB issue (or whatever they are called) or is it a more general stability problem. Suspend to ram is more important to me than compiz so if that breaks its not worth trying fglrx. The macbook pro site seems to suggest going to an older kernel might fix this: https://wiki.ubuntu.com/MacBookPro Can anyone comment? Many thanks, Sheer |

One more question: what mactel patches are still recommended? A lot of them have been moved into the stock kernel by now but should I still apply an appletouch patch to reduce power consumption or something like that? thanks, Sheer p.s. sorry if these questions have been covered many times before. I've been on the list for a while but its hard to find what has and hasn't been covered.

For the last few days I've been trying to use Linux exclusively on my macbook pro (see below for setup). I'm still using the radeonhd driver since fglrx doesn't seem to suspend even with SLAB. Unfortunately even with radeonhd suspend only works 5-8 times or so before I get a resume failing and I have to hard reboot. This is with 2.6.23+mactel patches on 64-bit ubuntu. I have the latest madwifi and uvcvideo drivers but I unload them before suspending. Does anyone have a perfectly stable suspend? I would be very interested in the details of such a configuration. I could live with the (not so) infrequent crashes if it was not for the fact that most of my data is on an unjournaled hfs+ partition that I share between linux and OS X. This partition has to be unjournaled or else linux can't write to it. When resume fails and i have to hard reboot the hfs+ partition has a flag set on it so linux can't mount it read-write so I have to boot into OS X and mount it there and then reboot into linux. Moreover, I'm very worried about my data on this partition since its unjournaled and hence more susceptible to corruption from a hard reboot. Does anyone else use a similar scheme and if so how have they resolved these issues? Has anyone tried using UFS as a shared data partition? Is it journaled? thanks, Sheer On Nov 2, 2007 12:17 PM, Sheer El-Showk <sh...@gm...> wrote: > Hi All, > > I've setup ubuntu gutsy with the amd64 kernel on my MBP 2,2 running > the radeonhd driver and so far its pretty usable.

I should add that my 2.6.23 kernel is custom compiled using Odi's config file whihc, iirc, enables SLAB instead of SLUB. I read here: http://ubuntuforums.org/showthread.php?t=564797 that SLAB makes the system unstable on resume so perhaps this is my problem. Does anyone have experience confirming this? Has anyone managed to get a stable config using SLUB either with radeonhd or amd's 7.11 drivers? thanks, Sheer On Dec 29, 2007 4:04 PM, Sheer El-Showk <sh...@gm...> wrote: > For the last few days I've been trying to use Linux exclusively on my > macbook pro (see below for setup).
