X11 Misconfiguration

x5x_tim · 2010-09-10 20:56:44

Hi,

It's been a while since my last Arch installation and I'm running into some problems.
When I try to run X without xorg.conf specified everything works. Problem is, resolution is all wrong and my screens are mirrored and stuff. So I want to specify some stuff in xorg.conf.
However, when I run Xorg -configure and use the generated file, I just get a black screen (well, two).

Here is the file xorg generates:

I'm using a card with a HD 4850, so I installed the radeonhd driver.
Could someone with a little more experience with X please give me a pointer here?
Very much appreciated.

you can do it in 2 ways:

List the resolution you want in xorg.conf (old and deprecated way)
or create a 10-monitor.conf under /etc/X11/xorg.conf.d/ and list it in there.

You do not have to do a Xorg -configure either.

Simply put this OR something along these lines in your 10-monitor.conf

I use two monitors and an ATI card, you will have to change a few things according to your setup.

Sorry if I wasn't clear.
I know how to specify resolutions in xorg.conf, I did a dualscreen setup on another machine before.
My main problem is that I just get a blank screen with this conf file. I'd like to get the base xorg conf file working before I make edits to it.
(Or did I not understand you and is it possible to use 10-monitor.conf without using xorg.conf so I can just run x without it?)

EDIT: I see you edited your post.
I'm going to try the monitor approach, thanks.

yes. since xorg 1.8, xorg.conf has been deprecated although it will be initialized *if available*.

I just use a 10-monitor.conf file without an xorg.conf.

T-Dawg · 2010-09-11 02:52:30

Display problems are almost always the vertical and horizontal refresh rates being wrong either for the monitors or the video cards. Try digging up your monitor manual and entering in those rates manually. Sometimes the logs can be helpful in finding these rates to.

x5x_tim · 2010-09-11 07:46:13

I was thinking it was a problem with the driver.
Is there a way to check which driver is being used? So I can see what driver X is using without xorg.conf/10-monitor.conf?

schen · 2010-09-11 12:24:39

Your driver is radeonhd. Nothing wrong with it, except it has been halted.

Now just put in your 10-monitor.conf

I know my driver is radeonhd, I was wondering if it's possible that another driver is being used when I have no conf files for X.
I'm not sure I get the rest of your post

Inxsible · 2010-09-11 15:20:07

try the xf86-video-ati driver. I use that for my HD2400XT Pro and it works well.

No, I don't think that's possible.

The rest of my post was to say to put the 10-monitor.conf into the xorg.conf.d and try it out. Also, try out xf86-video-ati like Inxsible said.

Oh yeah, I already did that and that failed. So now I'm going to try xf86-video-ati (if I can get it, the only ethernet cable long enough to reach my pc just broke)

x5x_tim · 2010-09-11 17:11:51

With the driver set to xf86-video-ati (just trying, couldn't really install it, just seeing if it's preinstalled) I get the error: no screens found.
With radeonhd I just get a blank screen

codycarey · 2010-09-11 17:22:42

Do you have 'core/linux-firmware' installed?

EDIT: Also, out of curiosity, is there a reason you don't want to use Catalyst?

x5x_tim · 2010-09-11 17:37:46

I have actually.
No, there is not. It's just that I have no internet connection now (You saw the other thread)

codycarey · 2010-09-11 18:15:04

Do you have two monitors hooked up to the card or just one? Did you try running X without any xorg.conf file present?

x5x_tim · 2010-09-11 18:27:16

Hi,
Two monitors to one card. I tried, that works. I installed xf86-video-ati now I've got wireless internet (thanks cody) and now I've actutally got two screens in xrandr when I start X without xorg.conf and 10-monitors.conf
I'm going to try to just make it work using xrandr

EDIT: yes, using xrandr's mode and right-of methods makes it work I'll just use that in my xinitrc file

Inxsible · 2010-09-11 18:36:47

xrandr is enough to set up the two monitors. but if both your monitors use a different resolution, then you might need EITHER a xorg.conf OR a 10-monitor.conf

x5x_tim · 2010-09-11 18:44:21

It workes fine with just xrandr now.
DVI-1 on mode 1920x1080 and DVI-0 on mode 1280x1024
And DVI-0 right-of DVI-1

Inxsible · 2010-09-11 18:49:15

Hmmm... interesting.

I just wasn't able to get the correct resolution on my larger monitor. They both came up with 1280x1024 even though my larger monitor can go upto 1680x1050. I had to define the modes in 10-monitor.conf.

Oh well...if it works for you....

Check in your Xorg.0.log if your resolutions are auto-detected or not, sounds like they aren't.

Inxsible · 2010-09-11 20:37:56

i know they aren't. That's the reason i had to create a 10-monitor.conf
