On my 5770 still the same extreme lag when scrolling chromium, and firefox maximized on my 1080p display in ubuntu 11.04. This is with tear free enabled, which really needs some performance improvements, at the very least when it comes to 2D rendering, which for non gamers is 99% of what they are using, and even gamers are probably using 2d rendering most of the time they are on there computer anyway.
Anyone using chromium I found a workaround for the terrible scrolling lag I just described, type in about:flags into the address bar, and enable the the option: "GPU compositing on all pages". This works very well other than some very occasional very minor rendering mistakes that comes with it being an experimental feature of the browser (I'm using the dev build of chromium and it has the option, not sure how long its been there and what releases its in).
Personally I went back to the free drivers using oibaf's ppa, which work perfectly for 95% of the tasks I ever do on this box......the experience is seriously so much less of a headeache than dealing with catalysts constantly changing issues. If dynamic power clocking worked right, there would really be no reason to ever go back to catalyst
But you have disabled sync to vblank in Compiz have you?
I didn't think we had a workstation (eg FirePro) product based on E-350 or any of the Fusion parts yet. Doesn't mean we don't want fglrx to work on your laptop, but it's when we say "workstation" we're talking about FirePro etc...
I'm actually a bit surprised that suspend/resume is working with the open drivers. The feedback I had heard was more the other way round, that we had a known issue with the open drivers but that fglrx worked. Will ask around.
I haven't had a chance to search through the unofficial bug tracker but if there isn't a similar ticket on there already it would be great if you could add one with system details. Suspend/resume is relatively more system specific than most functionality so a problem on your system may not mean the functionality is generally broken.
One advantage that the open source drivers have had is that relatively more of the development has been done on real production systems (after launch) whereas most of the Catalyst work has to be completed well before production hardware is available. This advantage may go away a bit as we try to do the open source development work earlier and provide support closer to launch -- we'll need to figure out the best balance.
I'm in the same boat with my E-350 Acer laptop. There is no suspend/resume with closed driver, but it works with open source driver. Unfortunately video is so bad with the open driver that I boot into Windows for any videos. I have logged the bug with Ubuntu (even though it is the same with all distro's - I have tried Mint, Mandriva, Fedora, etc), and have tried manually installing (and uninstalling) each version of Catalyst through 11.7. I even updated to latest bios. I will probably try 11.8, but I am not hopeful of it working. I have also tried all workarounds, including even the trick with debugging the sleep with the bios clock. Nothing. This will be my last laptop I buy without Linux preloaded!
It looks like ATI/AMD drivers are still buggy no matter whether closed or open source. Really disappointing.
Looking at buying a $90-ish card but I don't think I can risk it with an ATI card. Regardless of what I get, I wouldn't be able to sell it to get my money back.
I guess things are worse with mobile-based cards in which you have to worry about power management and the suspend features.
But, two strikes against it, is uselessness for trying BSD and less performance if you ever need to use wine.
Also, it sounds like video is another area where Nvidia, unfortunately, excels. I want to choose the open source option but performance is important to me. When one is just a general computer user, you go with what works, right? :-/
Another area is all the desktop effects, compiz, flash use, fs/window, scrolling, tearing etc. etc. issues I read regarding ATI catalyst AND radeon drivers.
I know Nvidia has its share but I don't know which is the worse situation.
to the folks bitching about suspend/resume: What suspend software are you using ? tuxonice or swsusp2 (or how is it called) ? I never had any luck with tuxonice and fglrx but swsusp2 worked without problems.
