T41p - Fedora Core 5 - Issues

[Dead1nside]

Hi there,

My first foray into Linux wasn't so bad. I ran Knoppix and qtparted some of my drive, to give me a 10GB partition for my Fedora install.

The install went well, not being very experienced I haven't straye from default options.

My screen however is running at 800x600 when it should be at 1400x1050. How can I resolve this. Trying to change the resolution gets me 4 differnt little screens all a bit blurred.

My other problem is suspend when the lid closes, or even just suspend never works. It won't come out of it, just a black screen.

Thanks for any help.

Without being right infront of my pc I can only give you some ideas.
for the 1400x1050 resolution. I had to edit (I use nano/pico) /etc/X11/xorg.conf and went to where the resololutions section is you should see 800x600 640x480 and you add 1400x1050 to the front of the line. or you may end up the harder way with a modline and that I haven't done yet my self. This is by memory and I am using Ubuntu at the moment. As for the blank screen on resume, Ubuntu resolves this by itself using vesa state saving and resuming. using vbetool. I wote a script in FC5/4 to do this for me I will see if I can find it.

Thanks very much for that, it'd be great if you could find the script.

Why doesn't X detect the resolution properly?

[tstadler]

My guess why not detected is that it isn't that common of a resolution.

Here are comands in one script I have used for suspend with the fglrx driver, uload the usb drivers to save power and also had some performance problems.
Need to be root to work, but since I am not runnin FC right now I can't test this so you may need to fiddle and you will need vbetool installed, I think it may be in one of the repos or off of sourceforge.
I am soon going to be converting back to FC after a 6 month run with Ubuntu.

modprobe -r ehci_hcd
modprobe -r uhci_hcd
# switch to a text console
chvt 1
# save the video card state
vbetool vbestate save > /tmp/vbestate
hwclock --systohc
#echo 3 > /proc/acpi/event
echo mem > /sys/power/state
hwclock --hctosys
# reset the video card
vbetool post
# restore the video card
vbetool vbestate restore < /tmp/vbestate
# switch back to X
chvt 7
modprobe uhci_hcd
modprobe ehci_hcd

Thank-you, I'll look into it/fiddle with it.

I've managed to get the resolution to be detected. But suspend still doesn't work, do you recommend using the ATI drivers or the open-source radeon drivers?

Thanks.

If you want the best performance with 3d games the propratary ATI drivers, for the best suport for suspend, and depending on who you talk to the radeon ones plus with the new xorg 7.1 the performance is getting even better. A great resource that may help with your suspend is http://thinkwiki.org TONS of info to help. I had lots of issues with Fedora and suspending and spent alot of time tinkering. It is also my unerstanding that recent 2.6.17 kernels have some issues with suspend that may cause issues to. Good luck. When I start working on this again I will let you know if I find anything.
