[ubuntu] Imac G4 800MHz screen brightness problems [Archive]

This may be a similar problem to one posted in an earlier thread, but that thread refers to notebooks, so I posted a new one. I recently installed Ubuntu 9.10 on this machine, but can find no discussion of this issue for this machine, which is not a notebook but rather that funny machine with the half-sphere based with a lcd panel attached to the top of it.

I cannot control the brightness on the screen. It seems to be set on maximum brightness. In the kde control panel for power management, there is a slider for brightness, but it is inactive, with the slider set in one position about 3/4 of the way up.

Also, when the screen goes into standby or suspend mode or off mode, it never turns off but starts showing strange patterns of colour in horizontal or vertical bars, and eventually sometimes settles down to near off, but some light (perhaps just the backlight) is still on.

I tried the pommed package but it appears to be just for notebooks. There are commands for backlight and fblevel to alter backlight but they dont recognize any devices that can be affected. xbacklight says "no outputs have backlight property".

I tired the nv driver that was installed by default, and also the nouveau driver from package xserver-xorg-video-nouveau. But I could not get nouveau to work. I will keep working on that, but I would hope that the stock nv should also be able to control the screen brightness and turn it off.

I have googled around for hours trying to find something that can be done.

I can't really use the machine like this. It would be disappointing if an entire OS had to fail because it cannot set the monitor appropriately!

You need a working xorg.conf file....

I would start with the open source nv driver. For nouveau I see a bug report..
https://bugzilla.redhat.com/show_bug.cgi?id=505161

I would just start with a simple config file and work your way up..

Let us please know if it works. Give us the output of (and paste it in the forum thread):
cat /var/log/Xorg.0.log

another one, if you want to fall back to framebuffer driver:

(check the XF86Config-4)

Why? What is in the sample you provided that is possibly relevant, but not automatically generated by Xorg at startup? The DPMS option? Well, I tried that already.

In any case, as requested I tried *exactly* your config file, as well as others.
(Your file identifies the bus address of the video card, which is different from mine, but which is apparently ignored anyway if there is only one video card).
I would just start with a simple config file and work your way up..With no config file, with a very simple one, and with yours, I get the same thing as originally described. From yours:

Are you saying that you have seen Ubuntu 9.10 running on an Imac G4 800 (I assume they are all the same, but if not, then one with the same video card, etc., as identified in the log file) in which you can dim the screen, and in which dpms works correctly?

How do you dim the screen? Does the slider in the kde system settings for power management work? Or is there some other way. On the Imac G4 800 that is.

I don't know if pommed is able to adjust screen brightness, it was written for Apple laptops, but you might want to try. They also try to give support for other Apple hardware.

sudo apt-get install pommed

If it cannot handle, I would send them an email asking for support.

I don't know if pommed is able to adjust screen brightness, it was written for Apple laptops, but you might want to try. They also try to give support for other Apple hardware.I mentioned in my very first message that I tried pommed without success, and also that from how it is described, it appears to be only for notebooks, not the imac g4 desktops.. I'll try to contact the pommed people.

You didn't answer my question (or anybody can answer it): has *anyone* got proper dpms and screen brightness control on the imac g4? If so, where is screen brightness adjusted? Does anyone have the slider for screen brightness in the kde system settings working?

I cannot always answer all of your questions. I do my best.Thanks. for your help. The question I was referring to, though, was

Are you saying that you have seen Ubuntu 9.10 running on an Imac G4 800 (I assume they are all the same, but if not, then one with the same video card, etc., as identified in the log file) in which you can dim the screen, and in which dpms works correctly?I assume you can answer this, and that the answer is no.

found one bug report about an ilamp 13", which monitor cannot sleep:Yes, we seem to have a few people with this problem, and no one who doesn't have the problem, as far as I can tell. I suspect everyone has it, but that amounts to only a couple of people, and that almost no one is really seriously trying to use Linux on a ppc imac desktop.

Strange however, that this fellow doesn't mention the problem adjusting screen brightness. To me this is also very important. Not for saving power on a desktop, but for usability. I will ask him if he has this problem as well.

nice link about dpms:Unfortunately, the "xset s" he talks about does not really result in much powersaving or screen dimming. It just writes the screen black, still a lot of light and power there. It is just the same effect as using a screensaver with a blank screen.

The vbetool he mentions does claim to set brightness, but not for ppc, as it appears to crucially use aspects of the PC Video Bios. (I actually tried to build it before I realized this).

You may want to try xbacklight

debian800:~# apt-cache search xbacklight
xbacklight - simple utility to set the backlight level

xbacklight =50 to set the screen brightness to 50%

xbacklight +10 to increase

xbacklight -10 to decrease

You may want to try xbacklightI tried it right at the beginning and in fact I reported above in my very first message that::
xbacklight says "no outputs have backlight property"

Bump.

Also interested if anyone can lower backlight or turn it off on an iMac flat-screen g4 800MHz. Maybee with an other linux-dist than 10.04LTS

in yaboot you add a "1" tro your Linux name, so if your partition boots with the name "Linux", you boot like this:
Linux 1

Tnanks. I was away for a while, so I reinstall my /-partition during that time. I get in to /etc/yaboot.conf and changes 'time out' from 100 to 1000, cos I didn't have time to see yaboot-promt.

When I press 'Linux 1' it just get an black screen, as then I had the Nvidia nouveau installed. :(

My yaboot.conf looks like this:

## yaboot.conf generated by the Ubuntu installer
##
## run: "man yaboot.conf" for details. Do not make changes until you have!!
## see also: /usr/share/doc/yaboot/examples for example configurations.
##
## For a dual-boot menu, add one or more of:
## bsd=/dev/hdaX, macos=/dev/hdaY, macosx=/dev/hdaZ

boot=/dev/hda10
device=/pci@f2000000/mac-io@17/ata-4@1f000/disk@0:
partition=11
root=/dev/hda11
timeout=1000
install=/usr/lib/yaboot/yaboot
magicboot=/usr/lib/yaboot/ofboot
enablecdboot
macosx=/dev/hda9

image=/boot/vmlinux
label=Linux
read-only
initrd=/boot/initrd.img
append="quiet splash"

image=/boot/vmlinux.old

PS. xgamma worked to change brightness.

change the xorg.conf file. Replace the "nouveau" driver by "nv". That should work.

*There are on xorg.conf in ubuntu 10.04LTS. If I make an xorg.conf, the iLAMP don't start. just a black sceen. Impossible to do anything!!!

*If I typr 'Linux 1' the iLAMP don't start, just a black screen.

That is a big problem to fix anything if ju don't even get an terminal to communicate with the machine.

/Cheers.

PS. will soon see if a maybe can go in true ssh..., when the screen is black.

MintPPC ?

No Ubuntu 10.04LTS. They have 'developed' so much, so much 'normal' old school, don't work so much any more. But on PC things work very so I have forgot a lot of 'juxing' with computers ;)

I notice something strange with my iLAMP. In http://en.wikipedia.org/wiki/IMac_G4 it say that there are an.
Geforce 4 MX with 32MB DDR gfx, but lspci give me:

0000:00:10.0 VGA compatible controller: nVidia Corporation NV17 [GeForce4 440 Go] (rev a3)

But for now 'NV' -drivers work, but it is not so nice...
