Help with brightness

KidNotorious · #1 8th August 2005, 01:25 AM

A while back my monitor just all of a sudden became darker, and I couldn't fix it while in Windows. Now that I've got Linux, I'm wondering if there's anything I could do to fix the brightness problem. I tried xgamma, and it would work but then when I restarted my computer it just went back to normal. My graphics card is one of those Intel Integrated ones, and I have already installed the drivers for it.

I need help bad.

You could add a shell script for xgamma to KDE's Autostart folder so it loads with the desktop.

For example, you could do this in a text editor:

Code:

/usr/X11R6/bin/xgamma

Then save the file in /usr/share/kde/Autostart.

Well, I don't particularly like KDE so I use GNOME. How would I do that in GNOME?

No clue.

Try /usr/share/autostart, then a reboot.

Now I'm having another problem, whenever I change the gamma settings on xgamma and then restart, it always goes back.

Code:

-> Red  1.000, Green  1.000, Blue  1.000
<- Red  2.000, Green  2.000, Blue  2.000

Code:

-> Red 2.000, Green 2.000, Blue 2.000

And then when I restart it says

Code:

-> Red 1.000, Green 1.000, Blue 1.000

Sorry for the double post, but xgamma doesn't work at all for me. I had another person I know run it on their box and it worked instantly for him, yet I can set it but nothing happens and it returns to default if I restart.

Have you tried posting your xorg.conf to see if anything's anomalous?

KidNotorious · #9 8th August 2005, 04:57 AM

Can someone please help me? This is really making me mad.

OK, I'm dead clueless on the xgamma front, but I did find out how to do Autostart in GNOME.

Control Center -> Session => Startup Programs
Add xgamma and that will start automatically. The difficult part, of course, is getting it to recall previous settings.

X.org Foundation Documentation excerpt for /etc/X11/xorg.conf

Monitor Section

Quote:

Gamma red-gamma green-gamma blue-gamma
This is an optional entry that can be used to specify the gamma correction for the monitor. It may be specified as either a single value or as three separate RGB values. The values should be in the range 0.1 to 10.0, and the default is 1.0. Not all drivers are capable of using this information.

If you edit your xorg.conf to have these gamma values, then restart X, your problems should be over.

KidNotorious · #12 8th August 2005, 05:34 AM

Ok I did that, and now when I run xgamma all the gamma values are up to 2, but I don't see any change.

Should I try raising the gamma or is my monitor just shot?

My only thought would be gently tweaking until you get it right. Just use the same settings in xorg as you did when your monitor worked right, unless you already did that.

My monitor broke before I got Linux. I really don't know what's wrong with it, I came home one day and it was really, really dark.

KidNotorious · #15 8th August 2005, 05:45 AM

I've got it set all the way up to ten, and still nothing. I guess I'll have to get a new monitor.

Thanks for your help, though.
