Red Hat enterprise 4 WS on DELL inspiron 6400


Hi all,

I got a Dell Inspiron 6400. I have installed a Red Hat Linux Enterprise WS 3 on it. Can have 1024x768 resolution. But I would like to have 1280x800, which is the maximum resolution that in Windows XP can get.

The monitor type is Dell E177FPm.
The chipset is Intel® 945GM.
Graphic Card should be Integrated Intel® Graphics Media Accelerator 950™

The moniter is not there in the Applications>> System Settings >> Display >> Hardware, so I choose Generic LCD Display >> LCD Panel 1280x800.

The graphic card I use VESA.

How can I let my Linux can have the same resolution as what I can get from Windows XP?

I will wait online, any advice is deeply appreciated!!!

can tell you your using the wrong graphics driver, vesa is a default/generic driver. enter 'lspci' (might need to use '/sbin/lspci' with redhat) in a shell and look through the output. also if you try 'dmesg' (gives the log of boot messages) in a shell the card should be found, check for any errors relevant to a graphics chipset or module. if the card is found and the right module isnt being loaded you will have to do some tests and edit a few files then restart X. may be a good idea (was for me, i found out the hard way ) to install emacs (my preference) or vim, that way you can re-edit the files if you cant get back into X and are stuck in a shell. post back any output that looks relivant.

http://linux-laptop.net/hosted/toshi...-fc5.html#i810

think most of it isnt relevant:

/sbin/modprobe i810

Next, edit /etc/X11/xorg.conf, commenting out the VESA driver line and putting in an i810 driver line:

Section "Device"
Identifier "Videocard0"
# Driver "vesa"
Driver "i810"
VendorName "Videocard vendor"
BoardName "Intel Corporation Mobile Integrated Graphics Controller"
EndSection

Then reboot.

only dont reboot, press control-alt-backspace (not delete) to restart X. you should have your display options, or you stuck in a terminal. if so use 'emacs /etc/X11/xorg.conf' to restore your settings and 'gdm', 'kdm' or 'startx' to get back to the desktop.
good luck

hi stan

Hi stan,

In red hat Enterprise WS 4, there is a setting like this:
Applications>> System Settings >> Display >> Hardware, choose card type there. I did try i915 or i810 before, but restart X, it tells me device not find, no monitor found, I need to re-edit /etc/X11/xorg.conf to get back x.

Seems your method to change xorg.conf is equivalent to what I do from that programme. Anyway I will test it out later on and post my result here again.

Thanks so much for the help!


Best regards,
Dunhill

does sound like its doing the same thing alright. try just the
/sbin/modprobe i810
line in a root shell and see what error message it gives back. could be the file isnt getting edited correctly or the module just isnt there to be loaded, doubt it though, it should be with your kernel. post back the kernel version just in case. if your using a kernel around 2.6.10 (i seem to remember there are some hal and udev dependancy issues before that) the updating should be simple, may be a quick thing to try if the module isnt there. keep your older kernel of course just in case.
no such thing as it doesnt work with linux, it doesnt have a choice

didnt notice it first time through, the link above mentioned the module that came with the system (fc5 but it sounds like your having the same trouble) didnt work. read a bit more about it and it seems to be a problem with the i810 module and the xorg 7. do 'rmmod i810' in a root shell to unload the old module, then go through all the packages in that link, the version numbers probably arnt the same but looking through other posts on the same prob it seems to have disapeared around august this year. if some of them arnt needed it shouldnt do any harm having them instaled, and give it another try.

here is that link again:
http://linux-laptop.net/hosted/toshi...-fc5.html#i810

try 'modprobe i810' first to make sure the new module loads ok, then edit /etc/X11/xorg.conf by hand to make sure its edited correctly, then ctl+alt+backspace. cross your fingers and it should be ok this time.
if it still doesnt want to work then it will probably need a lot of searching on google and trying different options. if graphics speed isnt an issue then you can edit xorg.conf to specify a higher reolution for the vesa module instead.
good luck with it

Yeah, dual boot, XP preinstalled, but need to use Red hat

Hi buddy,

You are right, I am using Dual boot. Any suggestions? I am fed up with the fatty fonts and buttons. What's more, if do a presentation using Projector, fatty is so ugly. not professional enough.

Thanks and looking forwards to your help!
