Ubuntu :: Where To Change X Configuration Options In Natty Without Xorg.conf
May 24, 2011
I need to add an option to my xorg.conf to enable "backing store", like this:
Identifier "Miserable Old SVGA"
But I don't have an xorg.conf file in Natty. There are several conf files in /usr/share/X11/xorg.conf.d/, but I'm not sure which one to add it too (I can't find the Device section in any of them). I guess I don't even know if the "BackingStore" option is valid in the latext Xserver.
I'm using a netbook with an intel GPU and a recent intel driver. In my .xinitrc, I have this command: xrandr --output LVDS1 --set "scaling mode" "Full aspect" But that causes a brief black flicker and stalls the login a little bit. I'd like to specify this in my xorg.conf or find some way for this option to be set as Xorg starts. I don't know what the xorg.conf equivalent option is, or even if one exists.
I just installed 11.2, and discovered when I went to setup my Logitech Marble Trackball, that there was no /etc/X11/xorg.conf file. After some Googleing, I created one using sax2, Edited it to add the appropriate parameters to enable scrolling using the ball, and all works great.
My question is if there is a more "correct" way to change the parameters, as the mouse parameters are obviously stored somewhere on the machine.
BTW, for those with a Marble Trackball, all you need to know about the xorg.conf setup can be found here:
I've just done a fresh install of Lubuntu 10.10 on an older Sony Vaio laptop. Having learned the hard way about editing xorg files, I wanted to create a backup of the xorg.conf file so that I dont have to do another install when I screw everything up. In a terminal, I typed
I have installed Kubuntu 8.04.2 on a USB stick with persistence to keep any changes I make after a reboot and it works fine. I then installed the 185 Nvidia driver to give me higher resolutions and it works fine.
But each time I reboot, my updated xorg.conf is replaced with the default xorg.conf that ships with that version of Kubuntu and a backup is made of my updated xorg.conf (the correct one) which looks like xorg.conf.20100409135913. I have to put the backup xorg.conf back in place to get my Nvidia driver to work with the correct screen resolutions again. Otherwise my screen resolution is too low.
What could be causing this behavor? I'm sure it not the persistence feature of the USB stick failing since a backup is made of my original xorg.conf.
I might add more information. The xorg.conf that gets changed after a reboot says "This file was generated by dexconf, the Debian X Configuration tool, using # values from the debconf database." #
1. What is the difference between files (xorg.conf and xorg.conf-vesa)
2. No matter how hard I try I can't change keyboard layout in xorg.conf-vesa (I change it in file ) but there is no actually anything changing, it starts to get annoying - for example - below goes my xorg.conf-vesa, if I uncomment and set line from
I'm trying to get the latest Lenny running on some old hardware (a Winterm 3150se). Everything is working just fine except for two things.
When Gnome starts, it comes up at 1600x1200 resolution, which is too high for my monitor. It shows a portion of the right side of the display, If I select Screen Resolution, it gives me a few standard choices, but if I pick one, it acts like it's trying to honor my request, then comes back as 1600x1200 again.
My xorg.conf file had no references to Modeline, so I added a 1024x768 Modeline, not really understanding where the selection I was given was coming from. Anyway, it didn't help.
I can see in the log file that right after the entry about using xorg.conf, it says 'Module "ddc" already built-in', which must have something to do with it?
My hardware supports all the usual video formats, at least it does when it's running WinCE. Is there a way to force the use of xorg.conf or can someone tell me why DDC is acting like it's "read only"? Is DDC a file somewhere?
My other problem is that the Winterm refuses to not try to boot from the flash memory thumbdrive even though it's formatted as a non-bootable device - it's my SSDisk. I have to boot without the drive in, then slip in in just as the boot process exits the blue start screen. I can live with this problem, since it might be dumb hardware.
I just system-upgraded (testing) to kernel 2.6.38. All seems ok, except that a few things I added to xorg.conf in the past (basically, keyboard language switch) have no effect anymore. My xorg.conf is still there, it is still the same as before, but the changes I did in XkbdLayout section have no effect. It seems xorg.conf is not used anymore. I assume new version of xorg uses a different configuration file, but I'm not sure.
I'm running the ubuntu based Green OS and cant get my video card properly configured. i've already gone through the forums to figure out what i need to do to get my ATI card working but my system wont let me access the xorg.conf file. i can see it using the the GOS file editor but it wont let me save the modifications. when i attempt to edit from a terminal window with su privelages it tells me that /etc/x11/xorg.conf does not exist. i've even tried booting into recovery mode and using the root instead of the sudo command. nothing i've tried will let me open the file.
I have the nVidia driver on my desktop kernel set-up but have to change /etc/X11/xorg.conf from nVidia to nv to get a X to run in Xen. Whilst this works, is there a way to tell Xen at boot time to use nv rather than nVidia so I don't have to edit xorg.conf each time?
I've read the how-tos (thank you oldcpu!) and wikis about how xorg.conf take precedence over the section configuration files in etc/X11/xorg.conf.d/, if it exist. I also understand that the xorg.conf can be partial. If it is missing some sections, these will be taken from the corresponding xorg.conf.d section config file. Currently I'm using a xorg.conf generated by nvidia-settings in one of my home machines, due to a dual-monitor setup. After generating xorg.conf, the device sections are:
My question is if the Option "UseCompositeWrapper" "True" will be used or not. In other words, if a section exist in xorg.conf then it's correspondent in xorg.conf.d/ will be completely ignored *or* only the lines in xorg.conf.d/ that already exist in xorg.conf will be ignored?
for some reason I got taping on touchpad is disabled after some software upgrade or something.I can enable it with synclient TapButton1=1, etc.. but have got to do it every time I reboot. Also, I don't have Xorg.conf file. Is there any way I can configure taping to work permanently ?
I installed debian 5 in a pc with a Intel 4 series VGA. The optimal resolution for the monitor is 1360x76, but the system does not allow that. I tried to change my xorg.conf, but got no success.In my xorg.conf I used this:
I tried to edit my xorg.conf to try and encourage Debian to handle my joypad better (stop recognising it as a mouse). However, it didn't work and i couldn't get back into X.So, i entered recovery mode and deleted the contents of xorg.conf,got back into X and then edited xorg.conf back to how it was.Right so far so good.Yet, now i cannot use the backlash key in keyboard shortcuts. I have a number of shortcuts set up to incorporate this key and they no longer work, neither in GNOME nor Openbox
I've been using ubuntu on a new desktop for a couple of months, but i had an old HP that was given to me in my basement. It has 384Mb of ram, and thats because i had a 256Mb stick laying around. I installed debian becuase it is more suited for older hardware (at least from what I've read). It installed fine, but it boots to a blank screen, and pressing ctrl+alt+F2 bring me to the command line. I checked /etc/X11/xorg.conf to change the driver to vesa, to find out my video card isn't even shown. I ran lspci and I found that it says my graphics card is Intel Corporation 82810E DC-133 (CGC) Chipset graphics controller (rev3) In the device section of xorg.conf, it merly says Identifier"Configured Video Device"
Been working hard on trying to get my Radeon 5870 to run in Debian Lenny (x64). I've installed the xserver-radeon, radeonhd & ati packages through the synaptics manager, but my xorg config file is completely without information:
I found in my xorg.0.log the the xorg ATI driver is failing ALL options.
Code: (WW) warning, (EE) error, (NI) not implemented, (??) unknown. [ 8.942] (WW) The directory "/usr/share/fonts/TTF/" does not exist. [ 8.942] (WW) The directory "/usr/share/fonts/OTF/" does not exist. [ 8.942] (WW) The directory "/usr/share/fonts/TTF/" does not exist.
I have used nVidia my entire linux life (about 5 years clean and sober from M$). Recently, I have switched over to an ATI Radeon HD 5550 card. After many trial and error setups, I finally got the resolutions and screens set properly with a xrandr command, which I have now added to a shell script in ~/.kde4/Autostart. It has worked for me for a while now, but I really would like to get it set in the xorg.conf.d files so that I don't have to wait that extra few seconds after login for the screens to fix themselves.
Is there an easy way to take what xrandr does and export it to the xorg.conf.d files? If my video card recognizes my default monitor as DFP2 and the tv that I only sometimes use with this computer as DFP1, how can I ensure that the login screen for openSUSE/KDE4 appears on my default screen (an issue that drove me nuts a few months ago when I tried Ubuntu to see what all the fuss was about)?
I am using the proprietary Radeon driver from the ioda repository. DFP2 is a monitor which has a optimum resolution of 1920x1200, and DFP1 is an 1080p HDTV. I can not reverse the output plugs for the screens even though my monitor is an HDMI monitor because I use the actual HDMI port on the video card to output audio to the television and the other plug is a DVI that I convert to HDMI for the monitor.
When i want to configure my touchpad on my dell inspiron 1525 with debian lenny then i got this message: gsynaptics couldnt initialize you have to set 'shmconfig' 'true' in xorg.conf or xf86config to use gsynaptics My touchpad is an alps and not a synaptics so far i can see. My xorg.conf is this: [URL]
wireless via Bluetooth ï¿½ 3-button laser mouse with scroll wheel ï¿½ resolution 1600dpi, adjustable on 800dpi ï¿½ range up to 10m ï¿½ computer with Bluetooth or dongle required ï¿½ 2x AA batteries required
I've got an i5 Macbook Pro, on which I've got Ubuntu 10.04, which I use 90% of the time (mainly for work).
I've added a few lines to xorg.conf to make the graphic card run cooler and thus get some more battery life. Sometimes, though, I do need full graphic potential, for which I have another xorg.conf prepared without those lines, so I can switch back and forth when I need it.
Currently, to change back and forth, I rename the files accordingly and reboot, which is a pain in the neck. I tried restarting gdm after switching files instead but it didn't quite work (maybe I wasn't doing it correctly).
So, fellow experts, what's the easiest and fastest way to switch between two different X11 config files?
