General :: Default Display Manager Experiment?
Mar 20, 2010
i wanted to do a little experiment here by changing the default display manger to something like Firefox or GIMP or another program..Since "Display Manager is a program"
Quote:
gnome.org: GDM is the GNOME Display Manager, a graphical login program. i should be able to replace it by with any other program

I installed 6.04 LTS on my machine and the upgraded to 8.04 LTS, and then 10.04 LTS. I was playing around with appearance settings and chose the highest level of window animation but this seemed to cause some sort of problem with gnome (the top bar of windows disappeared including minimize, maximize and close buttons). So I used command line to reinstall gnome (sudo apt-get update && sudo apt-get install ubuntu-desktop) and this fixed the problem, but because i didnt realize what i had done to cause it i tried to do the animation settings again, which messed it up and became unfixable by using the above command, so i installed the kde desktop environment using command line and chose to use kdm as the default display manager because i thought i might have to uninstall gnome and didnt want to lose all display managers. Later on i had another idea of how to fix my gnome problem, i chose the highest level of animation again in the appearance settings but when it asked if i wanted to keep these settings or use previous settings i chose previous which reverted back to the lowest level and the window bar came back!
Because i got this fixed i didnt want to use the kdm display manager anymore, so i modified the /etc/X11/default-display-manager file from /usr/bin/kdm to /usr/bin/gdm, at the time i didnt realize it was supposed to be sbin! so i restarted the computer and now it cant find the file for kdm or gdm because gdm is in sbin and kdm is in bin but its looking for gdm in bin. So i have been trying to use recovery boot up to edit the file, which is where my problem is: whenever i try to edit the /etc/X11/default-display-manager file to read /usr/sbin/gdm, it displays that i do not have write permissions and that it is a read only file. I have used sudo with every command, and tried nano and vi text editors.Long story short I need to edit the /etc/X11/default-display-manager file to read /usr/sbin/gdm but it will not let me due to "write permissions" even when im using root and sudo;

I'm using OpenSUSE as a guest OS in VMware. Display settings are 1400x1050@60Hz but I want to change them for 1440x900. Using root account I go to Configure Desktop -> Display -> 1440x900. The first problem is that I can't choose 60Hz, only "Auto" or "0.0". I click Apply and the resolution changes, but if I reboot the computer or just logoff... resolution goes back to 1400x1050. My card and monitor properties: [URL]. Another strange thing is that if I click Ok on the Card and Monitor properties (changing from one resolution to another), I can choose to "Test" it, and xfine2 appears but... it ALWAYS says "1400x1050". An screenshoot of xfine2: [URL].

I'm trying to set krusader as my default file manager. I have gone into System Settings > Default Applications > File Manager and changed Dolphin to Krusader.
When I plug in a flash card the Device Notifier pops up and I click on the device inserted. The choices I get are Digikam, Dolphin, and Do Nothing.
I click on "Dolphin" (hard coded it appears) and it looks like Krusader tries to start. I get the cursor with the bouncing krusader mini-icon and an entry in the panel, but then nothing happens. It all goes away and I'm left with a blank screen (wallpaper, actually).
I've chosen Krusader from the menu, so presumably the arguments to it are good. I have KDE 4.3.3 and krusader 2.0.0.

I have a 64 bit Ubuntu 9.10 workstation with two virtualized guest OSes using KVM/QEMU. Also both 64-bit. One is Fedora 12 the other is beta of Ubuntu 10.04.
The problem is that I would like to use a larger size display that is configured by default.
Both guest OSes have a maximum screen resolution of 1024x768. I would like to increase this to something like 1280x900 or 1440x900. The resolution of the host system is 1920x1080.
This configuration appears to be a result of the installation detecting the resolution being reported by the virtual screen during installation.
The only information I have found on the subject suggests modifying the xorg.conf file in the /etc/X11 directory. Neither guest system has this file.
I tried creating one by hand in the Fedora system and managed to render it completely unusable. Not a big deal as this is recently installed and can be reinstalled easily.

I set up an NFS server on my home computer, all very simple add a line to /etc/exports, run exportfs -a, all worked well and as expected. Through no fault with Fedora, bugs in the client computer made me abort the entire experiment. (long story that you don't want to know) Undo all the config, reboot. However I'm now left with an issue that's not earth shattering. Every time I reboot my computer a /Public directory is created in my home directory, this is obviously a legacy from the original NFS setup. I've trawled through log files, looked at config files in /var/lib/nfs, but can find nothing that might be generating this /Public directory at boot time.

I want to experiment with Hydrogen, Rosegarden and other music apps it seems that jack is a useful program to do that. I have a standard install of Lucid. When I start Jack, it gives a message "suspending Pulseaudio The jack apps I am using have no sound. I assume that I need to set up an ALSA device to connect Jackd to? Is that correct?
[Note: I found these instructions for "running Pulseaudio on top of jack" [URL].. but they look more complicated than I need. I'm only using jack a little each day so I am fine with turning off Pulse during those times.]
What is the simplest way to get sound out of Jack apps? If it is to set up an ALSA device, how do I do that without interfering with Pulse which will be running the other 90% of the time? Or am I totally misunderstanding the setup?

I am learning about linux memory and hugepages, and know that hugepages basically is just memory that manages memory. I thought I'd experiment with the subject, and wrote a very small C program [URL] that basically just eats 20 GB of memory. The idea was that I would use this small C program to see how big the page table would get when handling large areas of memory when I'm not using hugepages. After running the program on my RHEL 5 server I was expecting the PageTable to be huge, but found that it was only about 43 MB. The page size on my RHEL box i 4 kB. Why I'm not getting the major PageTable size issue I was expecting?

So when my laptop resumes from suspend (haven't tried hibernate) the screen is black (and stays black) until I hit ctrl-f7is this because its opening the wrong display, or because ctrl-f7 'wakes up' X, or ??? it's not that big of a deal, now that I know how to get back to the X session (at first I thought it was "frozen")but it is sort of inconvenient, is there a way to make the behavior "automatically go back to the x sesson on resume" ?

In WinXP, with the nvidia drivers, there's fan control.By default, out of the box, my NVIDIA 8800 GTX card's fan blows at full speed (noisy). So when I'm booting up and I'm in the BIOS.. it's at full speed and loud. Once Windows loads up (and the drivers kick in), the fan goes almost completely silent. It stays that way until I load up something 3D intensive.. basically it runs the fan as needed.Does the default display driver shipped with Fedora 12 do this out of the box?What about the nouveau driver?How can I see the nvidia fans' speed while using the default display driver?

I've recently started using burg (a modification of grub that shows pictures instead of/with text), and I really like it for booting into Ubuntu and Vista. After many failed attempts of trying to get OSX on my PC, I'd like to try Macbuntu (a theme for Ubuntu that makes it look like a Mac). Unfortunately (fortunately?) my parents have taking a liking to Ubuntu and hate when I change anything, so installing Macbuntu would be a big no-no. I made a copy of Ubuntu and will put it on another partition of my hard drive, but I don't want to have two Ubuntu pictures when burg boots up. Are there any bootup lines I can put inside burg.cfg to fool it into loading an osx picture, then loading Ubuntu?

I bought a new computer and installed ubuntu 10.04 about 2 months ago, and until yesterday it worked pretty well. Last night it acted kind of weird (slow, application would start loading and then just die) so I restarted the machine. That's when I understood that something bad happened.
When the machine starts and the os begins to load I get a bunch of text that says things like:
mount: mounting /dev on /root/dev failed: No such file or directory.
Same for sys and proc, there might be much more in the buffer but I can't seem to able to go up. I did not do any thing special last night and so I'm clueless of the reason for this. Also, since in this version of ubuntu the boot options are not displayed by default I tried pressing a key on boot in order to try another booting option but when I do that I just get the flickering cursor sign.

Recently I was creating an image in GIMP when I needed to add a new font. I went to my mounted XP drive and copied the file I wanted over into /usr/X11R6/share/fonts/TTF then I went to the font installer as root and installed the font system wide. After that I reloaded GIMP and the font was available. A little while later I went to browse the internet and when I loaded up firefox, it showed a properly formatted and spaced page with no text on it at all. If I highlighted a line, the invisible text would copy to the clipboard properly and I could read it that way. I figured it might've been a just a FF issue, but when I loaded up Seamonkey, I wound up with the same problem. I'm using Firefox 3.0.16 and Seamonkey 2.0.1. I tried going into the preferences and changing the default font, but no matter what I change it to, it doesn't fix it. Slack 1.2 running kernel 2.6.27.31-smp. I use slapt-get to stay up to date and as far as I can tell i have the latest patches and pkgs.
Code:
bash-3.1$ fc-cache -rv
/usr/share/fonts/OTF: caching, new cache contents: 23 fonts, 0 dirs
/usr/share/fonts/TTF: caching, new cache contents: 91 fonts, 0 dirs
/usr/share/fonts/Type1: caching, new cache contents: 64 fonts, 0 dirs
[code]....

I have a VM with Windows XP that is driving me crazy. Everything works great except the display windows (and networking, but that is a different story) I am open VirtManager and go to display the OS and the images will get distorted. I will open IE and scroll down a webpage and some of the text will remain still and others will move, leave an image of garbage. This makes it very aggravating to use. To clear the page I can shake the window (using the cursor not my hands) or move from one tab to another till it clears.. then if I scroll again I have to deal with it all over again.

I have downloaded a command line version of Ubuntu so I can install everything I want almost from scratch. Problem is, when I install an x display manager it wont let me login. It just flashes for a second with a cross, then returns back to the login screen...stuck in a loop."sudo startx" works but not "startx". I have tried lxdm and xdm.

In Windows Explorer detailed view I can select columns to display artist title, track number, etc for MP3 files. Is this functionality available under Krusader, Nautilus, Dolphin, etc? If so please help.
I downloaded a kde-multimedia package that was supposed to make this work in Konqueror but no luck.

Ok, I've tried Unity for awhile now and I can say it lacks a couple of critical things for me. First is launchers, second is a task bar. While casually browsing the web is ok, more serious work involving several windows has become a pain.
I have a dual screen with four virtual desktops. I'm tired of searching for my windows.
Now, I've read in a few places that I just need to choose "Ubuntu-classic" whenever I boot my machine. This is fine, but for the fact that I don't have any options on my login screen... Just the login and the accessibility & power buttons at the bottom right.
How can I log in using the old gnome display manager?

I have a pretty vanilla install of Ubuntu Lucid. I would like to change my default WM to sawfish. I have it installed, and it works routinely, I would just like to have it start automatically on log-in, rather than Lucid. A few sources have suggested that the way to do this is during log-in. They refer to a "session" I could choose, which would allow me to set the WM. I remember doing this in the past, but can't find such an option on the login page, now.
I have also experimented with changing .gconf/desktop/gnome/applications/window_manager/ using both gconf-editor and emacs. However, when I change "/usr/bin/compiz" to "/usr/bin/sawfish", log out, and log back in, I find that compiz starts anyway, and the setting in that file has been restored to compiz. Clearly, the gconf mechanism is getting the information from some other source.

I am using ATI HD3200 graphics card, and running Ubuntu 10.04 Lucid on a laptop. It have VGA port so I can attach external LCD monitor to the laptop. I am using fglrx driver.
My question is how should I configure the xorg.conf file so that when I attached external monitor, the GNOME menu bar (Applications, Places and System, etc) will be put on the external monitor instead of laptop LCD monitor.
I have checked varies web resource that saying you can drag and drop the GNOME menu bar to the new screen, it never worked. Someone also suggested to add new bar into the screen and GNOME will remember it, I can't even find the option to do that.
