Notes
*CPU frequency scaling:the applet shows 800MHz / 46% - are you supposed to be able to change it? Does it mean my CPU is running at half speed?
*Touchpad - scroll down side: It worked to begin with but at some unidentified point today stopped working, and logouts or reboots don't help. No idea why.
*External display: Fn-F4 doesn't trigger anything or even attempt to switch displays. There is no keycode output by showkey for this: I guess the BIOS intercepts or something - it's the same for Fn-F7/Fn-F8 which control the brightness, and the wireless on/off key.
*Sleep - Fn-F5 doesn't trigger any action
*Lock - Fn-F6 is supposed to lock the machine (I think) but actually it ejects the CD drive instead! Quite handy. On Dapper, it no longer ejects the CD drive, but doesn't do anything at all.
*Fn-1, 2 etc. bring up a small text box on bottom right of Nautilus window if it has focus - not sure what this is.
Please file these as bugs on Malone against 'acpi-support', along with the keycodes (use 'showkey -s' from a console) or ACPI events 'tail -0f /var/log/acpid' that occur when pressing each of the buttons. -PaulSladen
- will test in Dapper before filing bugs
*Screen res in Dapper: OK in install (after user selecting available modes during install); wrong in Live
USB mass storage devices work fine.
Video: totem-gstreamer DVD playback is slow and jerky (even with DMA enabled); totem-xine is fine - not sure if this is problem with this laptop's hardware, or totem-gstreamer in general.
Vodafone 3G card: I have one of these 3G PCMCIA cards and it works on Breezy with a bit of modules config, and on Dapper all that's needed is a pppd script to connect.
Hibernate (suspend to hard disk) option is offered by GDM and hibernate shutdown completed, however on starting ahead freezes after re-loading memory snapshot, and have to power off to and reboot normally. This works fine with SuSE 10.
Sleep (suspend to RAM) option not offered from GDM.
I don't believe there's a friendly way to configure external monitors for laptop in Ubuntu (either xinerama or mirror) and I haven't tried attempting it by editing xorg.conf. The laptop can manage to drive two monitors in 'mirror' config with OpenSuSE 10.
It's a shame the built-in cardreaders don't work, but I don't think there are any linux drivers around for these things anyway.
- How happily wrong am I! They work fine on Dapper!
