I have an RHEL5 machine which had a working X11 config attached to an old CRT monitor.The monitor has given up the ghost, so we tried to plug in an LG L1953T LCD display. Immediately we got the error "analog: out of range" on the monitor, which is not too much of a surprise, X in theory needs to be reconfigured.Googling showed that we needed to run the following: system-config-display --reconfig --nouiTrouble, is, this doesn't autodetect the monitor, and despite the updated xorg.conf file, the error remains.It seems that RHEL5 is capable of autodetecting the monitor during initial system setup, but for the life of me I cannot find a way to redo the X configuration process after the fact?Is reconfiguring Xwindows this difficult or am I missing something really obvious?Does anyone know what command must be run to autodetect and set up X?
After some more Googling I found the raw autodetect feature of X, like this:
X -configure
The resulting xorg.conf file correctly detects the refresh rate, as follows:
HorizSync 30.0 - 83.0
VertRefresh 56.0 - 75.0
This matches the spec on the monitor.
The monitor still doesn't work - analog out of range remains.
The monitor works fine when plugged into a Mac (using the VGA analog
port). Are LG monitors compatible with Redhat Enterprise?
Anyone have any ideas? Regards, Graham --
