[SOLVED] slackware 14.1 change screen resolution

Didier Spaier · 07-07-2014, 09:51 AM

Something seems a little weird: I don't see the module atyfb in the output of lsmod. Anyhow it should be a could one for your card according to "modinfo atyfb".

Maybe you videocard is not fully vesa compliant.

Remove /etc/X11/xorg.conf, do "startx" then look int /var/log/Xorg.0.log which driver is used. If it's not ATI then write an /etc/X11/xorg.conf fiel with just this:

Code:

Section "Device
  Identifier "mycard"
  Driver "ati"
EndSection

Then start X

Hello Mr. Didier,

Here is the following command I did on the Xorg.0.log file: "cat Xorg.0.log | grep driver". Here is the output of the command:

Code:

[   648.084] (WW) Hotplugging is on, devices using drivers 'kbd', 'mouse' or 'vmmouse' will be disabled.
[   648.084] 	X.Org XInput driver : 19.1

[   648.196] (II) Loading /usr/lib/xorg/modules/drivers/mach64_drv.so
[   648.332] (II) MACH64(0): Not using driver mode "1024x768" (hsync out of range)
[   648.332] (II) MACH64(0): Not using driver mode "1024x768" (hsync out of range)
[   648.332] (II) MACH64(0): Not using driver mode "800x600" (hsync out of range)
[   648.332] (II) MACH64(0): Not using driver mode "1280x1024" (hsync out of range)
[   649.917] 	ABI class: X.Org XInput driver, version 19.1
[   649.918] (II) Using input driver 'evdev' for 'Microsoft Microsoft 3-Button Mouse with IntelliEye(TM)'
[   649.921] (II) No input driver specified, ignoring this device.
[   649.923] (II) Using input driver 'evdev' for 'AT Translated Set 2 keyboard'
[   650.036] (II) Using input driver 'evdev' for 'Speakup'

I think it says ati_drv.so, so that must be the ati driver like you said. Correct? In any case, the Vesa driver loaded xfce with horizontal lines making it impossible to see the screen efficiently, but still I should try the ATI driver if you confirm ati_drv.so is like you said the ATI driver loaded without the xorg.conf file. So to load the ati driver I create a xorg.conf file from the xorg.conf-vesa file and change the Driver section of the Device from vesa to ati correct?

Waiting for your reply,
Dumdadum

We need to know which driver X eventually used (or tried), so please provide full Xorg.0.log (either inside [code] tags or as an attachment to your next post).

Also, assuming that it is actually MACH 64 (but this has to be confirmed) hsync should be properly set in /etc/X11/xorg.conf, and you could read /usr/doc/xf86-video-mach64-6.9.4/README to know more.

Here is the full Xorg.0.log file:

Thanks for the help,

When I look at your log I see that the X server is crashing. I have no idea why and don't assume it's due to a resolution problem.

Blind guess: you could use e.g. cvt to compute a modeline with the resolution you wish and put that in /etc/X11/xorg.conf. See "man cvt" and "man xorg.conf"

cvt? modeline? I dont understand? what is that exactly? if you say you dont know why the X server crashes, is it possible that I need to use huge.s instead of hugesmp.s?

Thanks for more info,

@dumdadum: If you want I can build a new package for you tomorrow, with the patch mentioned by Allend applied. Just tell if it's for Slackware-14.1 or Slackware64-14.1

Thanks. I'm using slackware-14.1, not the 64bit one... I appreciate. Itll be a .tgz or .txz package?

Thanks again,
Dumdadum

a .tgz probably, but that doesn't matter. I'll give the instructions for download and installation when it'll be ready.

Cool, and thanks again.

Cheers,

Didier Spaier · 07-11-2014, 04:53 PM

Do this:

Code:

lftp -c "mirror http://slint.fr/misc/dumdadum"
cd dumdadum
md5sum *md5 # answer should be "OK"
su # to become root (type root's password upon request)
upgradepkg --reinstall *xz

Remove /etc/X11/xorg.conf if you had one.

Then (re) start X.

Good luck.

PS Tell us if that works, I have no way to try it.

Thanks, I appreciate all the efforts. I'll try it on monday when I go to the office.

Well dear Mr. Didier, it works!!! Thanks for the patch. I'm marking this thread as solved. So freaking cool!!! (=

Glad it worked. I'll erase the patched package I provided as I don't wan't to keep stuff I will soon hardly remember what it is.

But for future reference for people with the same issue, here is the URL of the patch and in case that disappears here is the patch itself:

Code:

diff --git a/src/atimach64render.c b/src/atimach64render.c
index ffde2cb..8d259fa 100644
--- a/src/atimach64render.c

             break;

Instructions for use:

unpack this file from a Slackware mirror or installation media: source/x/x11/src/driver/xf86-video-mach64-<version>.tar.xz
check that the version of src/atimach64render.c in the unpacked archive be not already patched
patch it
re-pack the archive
run following command: src/x/x11/x11.SlackBuild driver xf86-video-mach64 to rebuild the package
upgrade using the new package
