Current Issues

DAPPER ISSUE SUMMARY

Latest test: Dapper Beta with all updates 11 May 2006

Bluetooth: my phone could see my Dapper laptop, but the laptop couldn't see in the discoverable phone with hidd --search. No gnome frontend available.

• There is gnome-bluetooth-manager, but it's currently lacking in functionality and doesn't do much more than just scan and display a list of pretty icons. gnome-obex or whatever it's called does allow you to receive files. -PaulSladen

• I can experiment with frontends but my main worry is that "hidd --search" doesn't find my discoverable phone. I used to have Bluetooth working fine under SuSE so I guess linux support is available for whatever chipset it is (it's built in to the laptop - not a USB dongle). -JulianRockey

Hibernate: sometimes works but sometimes seems to freeze with a blank screen whilst hibernating

• Does leaving the laptop a long time (eg. 5 minutes+) eventually allow it to finish and power-off normally. -PaulSladen

• I'll play around with hibernate a bit and report on findings. -JulianRockey

Hardware details

Notes

12 May: NEW REGRESSION: in latest Dapper (updates to 12th May 2006) the scroll-on-side-of-touchpad feature stopped working! It was working with updates to yesterday (13th May 2006). This is after a hibernate/restart so perhaps related to hibernation.

*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.

• Do they produce ACPI events in the /var/log/acpid logfile? -PaulSladen

• No. Bug #33045 -JulianRockey

*Sleep - Fn-F5 doesn't trigger any action

• This is marked as working above, please confirm whether it is or not -PaulSladen

• It's working - sorry, I updated the table above but not the comments here. -JulianRockey

*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.

• Please file this against hotkey-setup with the keycode and the action that it should perform and the dmidecode data for your laptop; see: LaptopTestingTeam/HotkeyResearch -PaulSladen

• Will add all DV4000 hotkey related stuff to bug #33045. -JulianRockey

• Works fine now in latest dapper. -JulianRockey

*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.

• Are they actually supposed to do anything on your laptop? Eg. do they have any small blue/gray writing on them or were they just in the template table and you haven't deleted them? Chances are they are just sending a normal 1 or 2 character which is taken to mean the start of typing a filename into Nautilus -PaulSladen

• Doh, of course. No they're not supposed to do anything. -JulianRockey

• 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

  • https://launchpad.net/distros/ubuntu/+source/acpi-support/+filebug

• will test in Dapper before filing bugs

  • Did you get a chance to do this? Many Thanks, -PaulSladen

• Yes, bug #33045 -JulianRockey

*Screen res in Dapper: OK in install (after user selecting available modes during install); wrong in Live

• Please file a bug against xserver-xorg and it'll be forwarded to the correct place. Please check that the video driver is also getting detected correctly and isn't defaulting to VESA as a fallback -PaulSladen

• This is working fine now. -JulianRockey

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.

• DMA likely won't make much difference since DVD video is less than 1 Megabyte per second and it's the decoding that takes the time; Any laptop faster than 400Mhz should be able to do it in software fine, let alone with hardware help. If you load xine from the commandline, are there any error or debug messages; if you find any that give an indication, please file a bug against xine -PaulSladen

• This testing was with GStreamer-0.8. I used Totem-Xine now and it's fine. I've not had a chance to test GStreamer-0.10 but from what I read I suspect this is a general GStreamer issue rather than specific to this laptop as consensus seems to be not as performant as Xine. -JulianRockey

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.

• Excellent news! -PaulSladen

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.

• SuSE ship with a different suspend system rather than the one in the kernel, which is the one we need to get working. Can you please file a bug against acpi-support with a report about whether Caps-Lock still works when it's frozen. -PaulSladen

• The above testing was with Breezy. Sleep works fine on Dapper. Hibernate occasionally has problems as noted above. I will test more and file bug with more info. -JulianRockey

Sleep (suspend to RAM) option not offered from GDM.

• This need to be whitelisted on a per machine basis. You can enable Suspend in /etc/default/acpi-support (it's the top option). If Suspend on your machine then works, please file a bug against acpi-support along with the dmidecode data used to identify your laptop. -PaulSladen

• It's working in Dapper (above testing was with Breezy). -JulianRockey

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.

• Yes, this is a missing feature, I think there maybe a Google SoC 2006 bountie on getting something working. If you get a working config, please file it in this page, or elsewhere so that it can be auto-configured when the right time comes -PaulSladen

• I'm hoping the Fn-F4 thing might work: am I right in thinking that laptops sometimes support this at the BIOS level so no X config might be needed? -JulianRockey

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.

• Above it says that the SD/MMC reader is working, please can you confirm whether this is the case or not, Many Thanks -PaulSladen

• Neither worked in Breezy. In Dapper it works fine for an SD card, but not MemoryStick. It takes other kinds of card too (MMS I think) but I don't have any to try. -JulianRockey
