Xorg config, X not allowing new resolution, works without Xorg config file?
This post is just to help me to get the X configuration correct. I have already read several of the posts with similar Xorg config issues, and they helped...but I have some additional questions to try to understand what is going on.
Slackware 12 KDE 3.5 I have edited the Xorg config file to add the new resolution and the wheel mouse. Then restarted X and X did not allow this new resolution. Then, I deleted the Xorg config file, changed a setting on the KDE Control Center for the monitor, and restarted X. The new higher resolution worked and the wheel mouse worked. There are two other files there that I did not edit: Xorg.conf-fbdev and Xorg.conf-vesa. Does someone know what is going on (does KDE not need Xorg config)? |
It will look for xorg.conf in multiple places...
I am no Xorg master, but have been always successful getting it configured by the RTFM method (I mean that as encouragement - not sarcasm!).
So look at man xorg.conf for starters, X looks for this information in numerous places and after you deleted the /etc/X11/xorg.conf, it probably just defaulted to another which has fortunate defaults. I doubt KDE has much to do with it at that point. For example (from man page): Code:
Xorg uses a configuration file called xorg.conf for its initial setup. This configuration file |
Perhaps I should have added that there is only one "xorg.conf" file in Slackware 12, and that after deleting it, there is no "xorg.conf" file, so even with the search path that you mentioned, X would not find an xorg.conf file. From other posts, a new xorg.conf file was supposed to be created and detected values filled in. But nothing happened, no new xorg.conf file was created ... but the mouse wheel worked, and the new resolution worked too.
Now, I am trying to understand why I do not need an xorg.conf file at all with Slackware 12 and KDE 3.5? |

(EE) Unable to locate config file (II) loader magic 0x<hex number> "built in default" screen automatically adding devices and enabling It finds the Video Card chipset and loads drivers. It finds the Monitor and finds what settings are valid, including V and H sync rates. It does not answer some new questions that come up, sort of puzzling at the moment. I'm sure there is an easy answer! Just can't think of it right now. If I pass a boot parameter: vga = 0x<new value>, Then it will not starx! It gives the error message: "Fatal server error can not run in framebuffer mode. Waiting for x server to begin accepting connections." And does not go into x. I am able to get the New Resolution and the mouse wheel works (as originally mentioned), without the Xorg config file...and reading the Xorg log explains the auto detect. It works if I do not pass other vga options at boot time. |
New X can start without a xorg.conf file. You can run (as root):
Code:
Xorg -configure Code:
Xorg -config /root/xorg.conf.new Regards |
