I booted on the Hardy Heron alpha 4 liveCD and installed from there on a 5GB primary ext3 partition.
No problem whatsoever during liveCD session and install. Everything went smooth. I have my home on a separate partition of course, and I created a "hardy" user just to play around.
Known Issues
EXA issues with intel graphic card driver (945, 965):
Hardy comes with the newest Xorg:
root@poliahu:/# Xorg -version This is a pre-release version of the X server from The X.Org Foundation. It is not supported in any way. Bugs may be filed in the bugzilla at http://bugs.freedesktop.org/. Select the "xorg" product for bugs you find in this release. Before reporting bugs in pre-release versions please check the latest version in the X.Org Foundation git repository. See http://wiki.x.org/wiki/GitPage for git access instructions. X.Org X Server 1.4.0.90 Release Date: 5 September 2007 X Protocol Version 11, Revision 0 Build Operating System: Linux Ubuntu (xorg-server 2:1.4.1~git20080131-1ubuntu3) Current Operating System: Linux poliahu 2.6.22-14-generic #1 SMP Tue Feb 12 07:42:25 UTC 2008 i686 Build Date: 19 February 2008 04:52:29PM Before reporting problems, check http://wiki.x.org to make sure that you have the latest version. Module Loader present root@poliahu:/#
and with X autoconfiguration (as far as I understand). So hardy installs a xorg.conf, but it is barebones. Most of the config is handled internally by the new server, and is handled fairly well. My screen and card were recognized, it configured it with the correct driver and resolution. I had 3D accel out of the box too, so that compiz was working without any tinkering. All good up to there.
The only problems I encountered in X (once more, this is only applicable to intel graphic hardware) were
(1) the trackpad was working but the scroll function was not (in previous version of ubuntu, moving your finger up and down in the right part of the trackpad would provide this functionality, here not). This is apparently a known regression (can't find the reference, but read it in some launchpad or ubuntu forum post). As it is a known regression, I assume it will be fixed for the final hardy release (?).
(2) The intel driver config adopted by default by the new xorg uses EXA acceleration, which is newer and performs overall better than the XAA. The problem is that on some intel hardware, it performs quite poorly for text processing. I noticed that immediately: when I had no window, or only a terminal around, compiz would be its usual smooth (e.g. when rotating cube or moving windows). With a few windows open, with text (e.g. firefox), compiz would be very jumpy / choppy. Copying over the xorg.conf form my gutsy installation and adding:
Option "AccelMethod" "XAA"
in the "Device" section (where the video intel driver is specified) solved the problem, and now I'm back to the old smooth compiz animations.
Using this -otherwise unmodified xorg.conf- had the side effect of killing my trackpad entirely. Now It's not responsive at all. Again, I expect these things will be ironed out for the final release. Another possibility would be to only add the XAA AccelMethod in the existing xorg.conf (hardy default), but I did not know nor researched how to do that.
[update 2008feb23: https://bugs.launchpad.net/xserver-xorg-video-intel/+bug/177492 describe the above problem. It turns out that there is another solution, keeping EXA. Keep the stock xorg.conf (the barebone one installed by default with hardy -clean install-. Just add:
Option "AccelMethod" "EXA" Option "ExaNoComposite" "false" Option "MigrationHeuristic" "greedy"
in the Section "Device" (so don't put XAA). With these settings, acceleration is smooth across the board (including wiht fonts) and compiz works like a charm. Cherry on the pie: you'll have XV (hardware video), so this means nice and smooth DVD and movie playing, much lighter cpu load, etc... compared to the x11 (software) video driver. As an extra, you can also use the INTEL_BATCH flag, which was reported by the vast majority of intel users to speed up graphical performance significantly (30%+). Put
INTEL_BATCH="1"
in your /etc/environment (I read you can also put it in your .bashrc, but I didn't try that). end update 2008feb23]
Multimedia keys don't work with Exaile
Another problem I noticed was that the multimedia keys were not operating in exaile. I haven't tested them in rythmbox or other apps.
Apart from that, everything I tested was fine: display, network (wired and wireless), sound (pulseaudio sounds noticeably better, but may be it's self induced), suspend (which worked for a couple of tests, and then I installed uswsusp -s2ram- 0.8, which has always been more reliable for me), haven't tried hibernate, nor bluetooth.
