Power Mac G3 Blue and White video resolution

**UniverseA7X** · January 27th, 2010

Hi guys, haven't been around here in a while, seems that the other OS section is completely gone, so I assume this would be the most appropriate place to ask this, since Debian and Ubuntu are similar enough.

Okay, so I installed Debian Lenny on my Power Mac G3. 450MHz, 1GB RAM, and an ATI Rage128, the stock video card. It also has a Linksys WMP54G Wireless card which I got working effortlessly enough.

My issue is with the screen resolution. The driver for the graphics card is installed, but I'm only getting a 800x600 resolution. My Monitor is a 1440x900 screen, so everything's quite out of proportion. I assume I may have to go into xorg.conf to tweak things, but I wouldn't know what to tweak.

This is the only thing I need to do to make this my full time OS on this machine. Your help is greatly appreciated.

Brandon

please post your Xorg.conf file...

I think you can use the ATI driver instead of framebuffer...I will post another Xorg.conf for you, just make your existing Xorg.conf a backup one:

Code:

sudo mv /etc/X11/Xorg.conf /etc/X11/Xorg.conf.old

sudo /etc/X11/Xorg.conf

now paste the following Xorg.conf in there

Code:

then you go to a TTY:

ctrl-alt-F1

login as root

then

Code:

/etc/init.d/gdm stop
/etc/init.d/gdm start

then post me the results of the Xorg log file

Code:

cat /var/log/Xorg.0.log

**linuxopjemac** · January 27th, 2010

I edited the Xorg.conf file, it had a mistake in there, in the modes section of default depth 24

**UniverseA7X** · January 28th, 2010

Upon restarting GDM, I'm getting an Xorg error, telling me xorg can't start:

Code:

              (++) from command line, (!!) notice, (II) informational,

Fatal server error:

Here are other warnings I get in the extended readout using the same key as in the above notice:

Code:

(WW)The directory "/usr/X11R6/lib/X11/fonts/misc/" does not exist. 
Entry deleted from font path

The same notice for the following directories:

/usr/X11R6/lib/X11/fonts/CID/

/usr/X11R6/lib/X11/fonts/100dpi/

(WW) FontPath is completely invalid. Using compiled in default.

/usr/share/fonts/X11/100dpi
/usr/share/fonts/X11/75dpi
/var/lib/defoma/x-ttcidfont-conf.d/dirs/TrueType

I'm typing all of this, if you need an entire read out of the file, I can run a reconfig of the xorg server and copy paste the entire file here. These were just the errors and warnings.

And thank you for already creating an xorg file, that was beyond what I expected.

Presuming you typed the whole error message we will delete the font stuff from your Xorg.conf file as probably the paths do not fit...you can try to find out later

That worked, sort of. The correct resolution now appears, and I was able to set it to the display's native 1440x900, but there's still a quirk.

There are vertical soft lines that run across the screen, and the fonts aren't smooth. It looks like maybe a refresh rate issue? I'm not sure. The only refresh rate I'm able to pick is 60Hz, and I know that the monitor is capable of 75Hz.

Also, there's a resolution available higher than 1440x900, and it's 1440x1024.

Don't know if this has any relevance, I just thought it was odd since it wasn't in the Xorg.conf.

**linuxopjemac** · January 28th, 2010

maybe HorizSync 30-107
VertRefresh 48-120
is not correct. What happens if you delete that section ?
