Monitor goes to sleep mode when I startx

[chefmn]

I am dualbooting WinXp and RH9, I have a HP ultra VGA monitor, radeon 7200, 5 button MS intelli mouse, (its USB with a ps2 adapt.) I installed RH in the GUI mode just to see if it would work, and it did, it loads fine to the text login, but when I run startx, the monitor goes to sleep, so i reboot, and run redhat-xfree86-config , once again monitor goes to sleep, I looked in the XF86Config file and everything looks ok, (but i dont really know what Im looking for), and I am either missing the path or syntax on trying to run XF86Setup or whatever it is.

i have looked all over the net, and cant find much on this?? any ideas??

thats in advanced for any help.

Sounds like either the resolution/refresh rates are out of range for the monitor...check your monitor specs against the settings in the /etc/X11/XF86Config

[jasonlambert]

Ok,

try these in sucession one at a time and checking to see if it works before moving onto the next one:

1: Follow the comment here: http://hardware.redhat.com/hcl/?page...tails&hid=2233

Failing step 1:

2: try doing startx, when it hangs try the following key combinations:
ctrl-alt-+ OR ctrl-alt-minus OR ctrl-alt-backspace

failing step 2:

3: run "startx > ~/.xsession-errors 2>&1 &" (minus quotes), then paste the contents of .xsession-errors in your home directory up on this site, and also paste relevant contents from /var/log/XFree86.0.log

Ok , step1 I am not sure how to do that, i looked for that file on all my Cd's, didnt find it. step 2, had no effect, step 3 i have the file, but im not sure what i am looking for in it,

Also, I forgot to say that there are 2 video cards in that PC, the second monitor never flinched during the install, but i figure i should tell you its there, it is an nvidia riva tnt2/ model 64 pro

i dont see any errors in that xfree86.0.log file,

also this may be of use, the ati radeon 7200 is PCI, and the nvidia is AGP, but the PCI card is the primary and the agp is the secondary. (in windows)

I ran this cmd and got the results below it

root@localhost root]# grep -i drive /etc/X11/XF86Config
Driver "keyboard"
Driver "mouse"
Driver "mouse"
Driver "radeon"

Thats what I get when I do that, Im using Grub, hope this helps.

did this in run level3, thoiught the info might help

I had a simaler problem once, the resolution had been set too high.

check your XF86Config file for the section that looks a bit like this...

Subsection "Display"
        Depth       8
        Modes "1024x768" "800x600" "640x480"
    EndSubsection
    Subsection "Display"
        Depth       16
        Modes "1024x768" "800x600" "640x480"
    EndSubsection
    Subsection "Display"
        Depth       24
        Modes "1024x768" "800x600" "640x480"
    EndSubsection
    Subsection "Display"
        Depth       32
        Modes "1024x768" "800x600" "640x480"
    EndSubsection

EndSection

change it so it looks like this

Subsection "Display"
        Depth       8
        Modes "640x480"
    EndSubsection
    Subsection "Display"
        Depth       16
        Modes "640x480"
    EndSubsection
    Subsection "Display"
        Depth       24
        Modes "640x480"
    EndSubsection
EndSection

and then try startx again. if that doesn't work then you need to find the verticle refresh and ghorzontale sync of your monitor (tell us the model of the monitor and i'm sure we can help with that)

if that does work then you can try putting in a higher resolution into the 'Modes' lines. keep goign untill your monitor goes into standby on startup again. and then go back to the highest res that worked.

hope this helps.

i did this and it worked,


cp /etc/X11/XF86Config /tmp/xcfg
sed 's/"radeon"/"vesa"/' </tmp/xcfg >/etc/X11/XF86Config
rm /tmp/xcfg


I am assuming that that is switching the radeon driver out for some sort of generic driver, ??

[sarumont]

Yes, chef, that line is telling X to use the radeon driver as opposed to the generic vesa driver. Glad you got it working.

[jakedawg]

its amazing how similar our setup is chefmn.

I too am having the same problem.

I am trying to dualboot rh with winxp, I have a radeon 7000 on PCI with another graphics card built into my motherboard, my mouse is usb with a ps/2 connector, and my monitor goes dead when linux is done loading.

Im pretty sure its not the resolution being set too high because my monitor displays a message when thats the case (such as when i connect my computer to another computer with a res higher than 1024x768 or when i installed college linux and defaults the res to whatever it was)

I dont know what im doing and i dont get the command prompt before it loads because i think it starts xwin for me. I probably could get to the command prompt if i press some buttons during the bootup. I havent tried to yet cuz i dont know what im doing.

could you explain exactly what you did. Or someone who understands this explain it. what did you type and when?

all of you pro's retarted worshipper,
