I've been waiting for OpenSUSE 11 to install it on my notebook for a while hoping that 11 would solve my WLan issues. Here are some first impressions:
WLan: It finally works although it needs some tweaking. For my WLan I need WPA2 which is supported by the on board NIC. Unfortunately, neither the ath5k nor the ndiswrapper driver manage to get it working, both of them fail during the 4-way handshake. Even more frustrating is the fact, that the 'official' madwifi-kmp package doesn't match the kernel and thus can't be installed. (I guess, they'll fix it soon.) But there's a solution (as root):
rpm -Uvh /path/to/madwifi-kmp-default-r3725+AR5007EG_184.108.40.206_1.1-2.2.x86_64.rpm
Sound: Same problem as in 10.3, just add
options snd-hda-intel model=lenovo
Graphics: Works fine as long as you use the NVIDIA drivers. (OpenSUSE.org: NVIDIA) They're proprietary but I can live with that for the moment.
Webcam: Untested, I don't need it.
Other devices: Didn't notice anything bad and contrary to 10.3
doesn't return any 'Unknown device' sections. (But these didn't cause me trouble in 10.3 either.)
Stability: I've chosen to use KDE4. The installer warned that KDE4 might not be as stable as KDE3.5 (one of the alternatives) and that's true. But it's stable enough to be used. It hasn't crashed (yet) but sometimes it's irreproducably slowing down some (never all) applications. (Like needing 10 minutes to open an extra tab in konsole. Funny enough, it didn't affect opening a new konsole window.) Another thing is that some icons in the control panel get lost during each session.
Wish you long days and pleasant nights,
UPDATE: Today the keyboard of my notebook refused to work or (more likely) KDE4 didn't process it's input anymore. Only solution I came up with: Save everything (mouse still worked, thank god) and reboot. Now everything is fine again.
