I installed Fedora 6 on my T60 widescreen and cannot get the resolution to display correctly. I also cannot get the wireless to work (Atheros a/b/g/n). Does anyone know how to solve these problems?

Thanks.

It doesn't detect your resolution first time? That requires the editing of a file, which I'll remember in a second.

As for the wireless, you need to download the Madwifi drivers which deal with the Atheros chipsets.

Yeh, sorry I can't remember, I stopped trying to get Linux to work myself a while ago, amazing how quick it's left me.

Should help you at least for your wireless problem. It is just a case of editing the '/etc/X11/xorg.conf' file and changing the resolution in there to the proper values, that you would like. Then restart X, there's a shortcut to do that but I've forgotten that too, so you'll have to restart.

EDIT: or the fglrx driver might allow that to be configured easier, that's the proprietary ATI driver. Instructions are on that web link.

I'm running FC6 on my T60... not widescreen.

Do install the ATI driver and madwifi.

Updating madwifi is still a little crazy at this point. If "yum update" gives me a new kernel, I do this:

yum --enablerepo=atrpms install madwifi-kmdl-`uname -r`
(those are backticks)

after a reboot, but that requires wired access.

Do you get good signal with the Madwifi drivers? I've found them on my T41p to be lacklustre.

I get good signal strength and range so far. I have yet to try it outside though (snow today!).

If you can not select the proper screen resolution from Display program, or it keeps switching to a mode you don't want the easiest way to do this is to edit the /etc/X11/xorg.conf file and modify the following:

First at a command line prompt type:
> gtf X Y refesh
where X Y equals your resolution and the refresh equals the refresh rate (select 60, as if I remember correctly refresh rate doesn't apply to LCDs).
So for typing:
> gtf 1920 1200 60
you should get output that looks like this:
Modeline "1920x1200_60.00" 193.16 1920 2048 2256 2592 1200 1201 1204 1242 -HSync +Vsync

Copy that line into the xorg.conf file under the Monitor section:
Section "Monitor"
Identifier "monitor1"
VendorName "Generic"
ModelName "Flat Panel 1920x1200"
HorizSync 31.5 - 90.0
VertRefresh 59.0 - 75.0
ModeLine "1920x1200_60.00" 193.2 1920 2048 2256 2592 1200 1201 1204 1242 -hsync +vsync
EndSection

Next in the "Display" SubSection under "Screen"
delete all modes except the resolution you want to use.
ex:
Section "Screen"
Identifier "Screen0"
Device "Videocard0"
DefaultDepth 24
SubSection "Display"
Viewport 0 0
Depth 24
Modes "1920x1200"
EndSubSection
EndSection

save xorg.conf. and press ALT+CTL+BACKSPACE -- this will restart X, make sure you have saved everything as you will loose everything open when you restart X.

The default generic video driver should work for all resolutions up to 1600x1200 (UXGA) -- I could set 1920x1200 WUXGA, it would just be ignored and default back to UXGA. I had to install fglrx to get 1920x1200.

Also, if you need (or want) to install fglrx for FC6, I would HIGHLY reccommend saving yourself some time and getting the prebuilt stuff from http://rpm.livna.org/-- it uses yum to install packages, so it is easy.
