Ok nobody else is responding so I will take a shot. I don't have anything like this setup but I did have some trouble in this area. I installed with a simple 15in monitor and then moved the system to my house which had a Dell flat screen. Well the flat screen displayed 'mode not supported'.
To solve the problem I had to do the following: <ctrl><alt> <backspace> - several times. This will eventually drop you to the dark place at the login prompt (I repeat SEVERAL times I had to hit the key combination) login as root at the command prompt: redhat-config-xfre86 -reconfig This causes the video configuration system to start from a VGA setup and deletes all the old configuration information. This allows you to start from scratch and define your monitor as you want. The -reconfig option deletes all the existing stuff and forces a fresh start. This may or may not work for you but it worked in my situation. Like I said I don't have your setup but it is worth a shot.

I'm trying to use a VGA to TV converter (Guillemot, maxi converter pro) that accept 31 to 35.5 Khz of horizontal frequency and 50 to 70 Hz vertical frequency. I tried it under windows with 2 different machines and it worked very good even in 800x600@70 hz (37 Khz hfreq) Unfortunatly, when I tried it with my RedHat, a strange image appeared on my TV when X was loaded. The bios, boot and console show correctly my on TV, but not X. I tried a lot of resolution, even by limiting X to 31.5 Khz and 60 Hz (VGA standart) with a resolution of 640x480. But it didn't work. How I know the tested resolution ? Well the converter is also a passthru and can display the real VGA resolution while converting it to TV resolution. So you can have 2 screen showing the same thing: the TV and the monitor. And as my monitor can tell me which resolution I use, I looked every time. Moreover, I tried with other linux distrib (Vector Linux 2.5 and Peanut Linux 9.3). And as soon as I put the correct frequency values in XF86Config, it worked very well. So I copied the XF86Config used in both distrib and tried them with the RedHat 8.0. But it didn't work. The resolution get changed and I could see the good resolution and frequency on my VGA monitor, but the TV display was out of range (the TV showed a very bad and strange image of what I saw on the VGA monitor). So it is really a RedHat 8.0 matter, not a XFree 4 problem. So I really need help... What the matter in the redHat 8 default config ? Where the modelines are stored (I can't see them in XF86Config) ? -- redhat-list mailing list unsubscribe mailto:[EMAIL PROTECTED]?subject=unsubscribe https://listman.redhat.com/mailman/listinfo/redhat-list
