R30 Thinkpad install, screen resolution issue in X

[Maurice F. Piller]

I did a fresh install of FC2T3 on an IBM Thinkpad R30.  Install was successful.

Reboot after install and X came up in 640x480 even though my hardware is a
1024x768 LCD screen and I selected Generic LCD Panel -> 1024x768 during X
configuration.

Tried to get 1024x768 graphics using the gui tools "System Settings ->
Display"
and "Preferences -> Screen Resolution" but this did not work.

After some time I fixed the screen resolution problem by manually editing the
/etc/X11/xorg.conf file.

Everything else looks good so far; network autoconfigured, sound works (after
adjusting volume using keys on my keyboard), gnome looks great, and Google is
now the mozilla default setting for Internet Search!

Used up2date successfully, it seems to be more responsive that in the past, it
complained about GPG signatures.

I got the same problem with my Nvidia Geforce 4, except that half the
time it was in 1024x768, half the time in 640x480.

It appears that the new system-config-display doesn't enable the hard
coded screen settings in your /etc/X11/xorg.conf.  Instead, it relies on
DCC probes.  My monitor/card combination has some problem, and the DCC
Probe fails half the time.  To work around this, edit /etc/X11/xorg.conf
and look in the Monitor section.  Uncomment the HorizSync and the
VertRefresh lines.

Section "Monitor"

 ### Uncomment if you don't want to default to DDC:
    Identifier   "Monitor0"
    VendorName   "Monitor Vendor"
    ModelName    "Lite-On A1770NSL"
    DisplaySize  320    240
 ### Uncomment if you don't want to default to DDC:
    HorizSync    30.0 - 69.0
    VertRefresh  50.0 - 120.0
    Option      "dpms"
EndSection

Hope that helps.

I have to see yet a non-x86 machine where DCC probe works.  Even on
x86 boxes this is very iffy in my experience.  Luckily there is
still something to comment out but people with an editor fear
may have a hard time.

Same here on Dell Latitude - I bugzilla'd it:
