Lost logout shutdown/restart options after Beryl [FIXED]
When I installed beryl using the instructions on this page, everything worked great (thanks!) except I lost the shutdown and restart options on the logout screen. This seems to be a common problem re. this thread at ubuntu forums: http://ubuntuforums.org/showthread.php?p=1947679#post1947679.
From advice in that thread I changed my /usr/local/bin/startxgl.sh to this:
#!/bin/sh Xgl -fullscreen :1 -ac -br -accel glx:pbuffer -accel xv:pbuffer & sleep 4 export DISPLAY=:1 cookie="$(xauth -i nextract - :0 | cut -d ' ' -f 9)" xauth -i add :1 . "$cookie" exec gnome-session
...which got the shutdown and restart options back for me. You might consider adding this to the instructions if it's not too much of a hack.
Thanks very much for this guide! Mgrusin 18:44, 30 December 2006 (CET)
Thanks, worked for me too! I've modified the tutorial accordingly. Keithvassallo 22:50, 02 January 2007 (CET)
Power Management Issues
Is anyone having problems with Suspend to Disk? It's suddenly stopped working for me...
Re: Problems with Suspend to Disk
What problems exactly?
-freeze while suspending or
-freeze on wake up
-doesn't do anything if you press the suspend key combination
My Keyboard Suspend shortcuts stop working if I don't login with gnome, because the acpi_fakekey script launched doesn't work outside of gnome.
pmi action sleep
pmi action hibernate
The problem I'm having is that suspend to RAM only works sometimes - the other times it just crashes. Suspend to disk just doesn't work - just crashes all the time.
What script are you using? I'm just using FN+F4 and FN+F12, or right-clicking on the power manager and selecting Suspend or Hibernate.
I'm having suspend / hibernate problems but it's not "suddenly" since this is a fresh install (edgy 6.10, T60p). My symptoms are upon suspend/hibernate, the screen goes black and the moon LED starts blinking but never stops. It won't wake up from this state without a hard shutdown.

UPDATE - SUSPEND WORKING: I got suspend to work by following the instructions in this ubuntuforums thread: http://www.ubuntuforums.org/showthread.php?t=274511. Briefly powernowd needs to be stopped before suspend and restarted afterwards.

UPDATE - HIBERNATE WORKING: I got hibernate to work by adding the resume= parameter to the # defoptions line in /boot/grub/menu.lst. This parameter should point to your swap partition (mine is /dev/sda6). Note that you do not need to uncomment the line:
## additional options to use with the default boot option, but not with the ## alternatives ## e.g. defoptions=vga=791 resume=/dev/hda5 # defoptions=quiet splash vga=791 resume=/dev/sda6
Note: I thought I needed to run update-grub after making the above change to the menu.lst file, but when I did so it erroneously changed the boot partition numbers further down in that file so grub no longer worked correctly (I needed to boot from the livecd to fix it). I recommend either not running update-grub, or if doing so, double-checking the menu.lst file for proper partition numbers before rebooting.

I'm having the exact problem as Mgrusin. Using PMI doesn't work either. I do think the issue is related to fglrx drivers. I'm going to wait for the new version though. According to several tutorials, using suspend2 seems to solve the suspend to disk issue. However, I had tried that with an earlier Ubuntu installation and bricked it, so I'm not trying again!

Maybe some of the scripts in /etc/acpi/suspend.d prevent your system from suspending.
if you don't know how how Suspend to Ram in Ubuntu works read the following lines (else jump forward to Finding problems)
How Suspend in Ubuntu works (light version):
however you prefer to suspend in Ubuntu, all ways will lead to
first of all speep.sh will get some Varables (about screen lock, power management,...) by calling
/etc/default/acpi-support /usr/share/acpi-support/power-funcs /usr/share/acpi-support/device-funcs /usr/share/acpi-support/policy-funcs
will execute all scripts (*.sh) in
and then suspend with
echo -n $ACPI_SLEEP_MODE >/sys/power/state
($ACPI_SLEEP_MODE is "mem" in case of suspend to Ram)
Your notebook is now suspended.
Waking up works similar:
calls all scripts (*.sh) in
disconnect all USB Storage media and try a simple
echo -n "mem" > /sys/power/state
(wake up by pressing fn or closing and reopening the display)
if that works
backup all the scripts in /etc/acpi/suspend.d (and /etc/acpi/resume.d) and remove them.
Then try suspending with your fn keys or
pmi action sleep
if that works too, copy back the scripts one by one, trying if suspend still works
(of course you could also test the scripts one by one and see which one doesn't work)

Problems with ALt-Gr
My Alt-Gr key doesn't work in Beryl. I think it's a problem with loading the right keymap.
my solution is a small workaround: loading your preferred keymap with gnome, by adding the following script (save in /usr/bin/restorekeymap) to gnome startup programs
#!/bin/bash setxkbmap -model pc105 -layout de -variant nodeadkeys #if you use the .Xmodmap file for other stuff too uncomment the following line #xmodmap .Xmodmap
Replace keymap model, layout and variant with the one you prefer.
Please let me know if there's a better Solution
Video in Beryl
anyone else suffering under extremely slow video in Beryl? All Video players seem to require much more resources in Beryl. Anyone else experiencing the same Problem?
Kaffeine(Xine) slows down the whole system (on my 1.7GHz Banias) and sometimes kaffeine freezes. Mplayer works better, but still keeps the cpu usage on ~90% on fullscreen.
Doing something with tpb OSD makes it even worse. Changing volume in many cases permanently freezes kaffeine, and results in temporary 1fps in mplayer.
I tried all available Video output Plugins (xv, opengl,...) without noticing a difference.
Resolution not changing with external screen.
I've installed the ATI Drivers as described, but there's a problem:
An external display with 1280x1024 resolution connected via Docking station shows 1400x1050 pixels, so i can't see the whole screen. Is there a way to change the resolution automatically, depending on which display is active?
