Fedora :: Killing Xterm Causes A Permanent Black Screen
Sep 8, 2011
Our Fedora 15 linux box have the following requirements:
1. Runlevel 3
1. Autologin as root for convenience
2. Run Xorg
3. Run xterm on display :0.0
4. Lauch our program on display :0.0
So we simply put step 2 ~ step 4 in the .bash_profile of root user:
# .bash_profile
if [ -f "/.bahsrc ]; then
.~/.bashrc
fi
export DISPLAY=:0.0
Xorg &
sleep 3 # for some reason, we need this three seconds to make sure that xterm start up successfully
xterm &
The problem is, if I issue "kill xterm", it flashes out some messages disappearing so quick that I can't even read, and then leave me with a black screen with a cross cursor at the center. The system seems to be crashed, even the numlock doesn't work. Since we execute xterm & during logging in, now I can crash my system simply by pressing ctrl + C ! That's disaster!

I have a problem that I'm not sure how best to debug. About every other time when I boot my system, I get a condition where listing the files in /root locks up that xterm session.This can be cleared by opening another xterm window and killing the listing command. This happens on "ls -a", "find", "tar" and I think "stat" also. The locked up xterm echo's chararcters but does not respond to any control sequences. This is new with FC11.This has only been seen to happen for root. And once a system is booted with this problem it seems to persist until you get it booted without the problem.

I tried out many distros on my desktop before experimenting with my oshiba Satellite A665 laptop with integrated intel graphics. Everything worked out as normal until I was testing Ubuntu on a live cd, I clicked install and it sent me back to the login screen before I had made an account. So I then chose to restart and it started glitching so I had to manually power off. Ever since then whichever distros I try to install, they face numerous errors. On Ubuntu and Peppermint they freeze on the 5 dots installation part and Linux Mint just has a permanent black screen. Even the current Peppermint OS (only distro i have)hangs on the 5 dots when trying to boot onto the computer. This has resulted me in a computer that cant do anything, i've tried the noquiet and nosplash options but they don't seem to work. I was thinking of installing Windows and maybe erasing the disk by installing another distro later?

I was messing around with the screen orientation and thought it would be funny to orient it sideways. Big mistake The screen went black.I can force a shutdown, login and I get the same black screen. I tried hooking up an external monitor and the monitor showed no input so I'm guessing my laptop doesn't have that capability with Fedora.This is my main computer.

I downloaded Fedora-14-i686-Live-Desktop.iso and used the Fedora liveusb-creator to put this on a 2GB USB stick. Everything seemed to have gone well and it said complete; however, when I try to boot from the USB stick, I get a black screen with a linux copyright notice at the top and it just stays at that screen forever. I tried this on two computers with the same results.
I'd previously tried with Ubuntu and had a similar issue, it would go to a purple (if I remember correctly) Ubuntu screen and it sat that forever.

This problem started within the last few minutes. I run a program in my browser that uploads data from my machine (ubuntu) to another machine (Fedora 13), for manipulation and then spits back the data that does not match our standardised information.
When I tried to run it a few minutes ago, it seemed to take a long time to make the connection. I went back and checked the machine, everything was connected and fine. I decided to reboot the machine from within KDE and then try again. Same result. I went to the machine again and tried to login through KDE, the screen goes black for a few seconds and then returns me to the login screen. I switched over to a virtual terminal and was able to login using the same credentials. I checked the .xsessions-errors file and this is what I am seeing:

I want to kill parent process after "fork()" method. but if I kill parent process with "exit(0)" method, main() thread is terminated as well so child prosess doesn't work anymore. Is there any way to kill only parent process without affecting to child process?
#include <sys/types.h>
#include <sys/stat.h>
#include <fcntl.h>

Opensuse 11.3 with latest updates
KDE desktop
Whatever resolution I choose, 1600x1200 is preferred, it is reset to a default of 1024x768 when I log out. I use the "Configure Desktop" option to set the resolution. I can find no other method to do so. The graphics adapter is an ATI hd3200. I have installed the fglrx driver. I cannot fine the "Control Center" for the driver. How do I make the selected resolution permanent?

Start xpdf or gv. Click an xterm to be active and slide it over xpdf/gv. Vertical lines from xpdf/gv under the xterm stick to the xterm window above and make it unreadable.
The problem does NOT show with KDE default settings with display effects on but does show in fvwm, xfce etc, and in KDE without effects.
On a system with a Sandy Bridge integrated graphics (i5-2400) the problem went away by downgrading to xf86-video-intel-2.13.0. But it was not enough for another system with 945G which needed downgrading to xf86-video-intel-2.12.0.

I downloaded a bunch of updates with PackageKit, afterwards I had to restart. Now when I did, all I would get is a blank screen, no blinking prompt line or anything. I did a cold boot and the same thing happened. So, I tried it a third time and all is fine. I'm running FC11 and I'm glad everything is back to normal,but what might have caused this in the first place?

As a newcomer to Linux I recently installed F12 (2.6.31.5-127) from a full installation DVD and all worked well until I decided to download a bunch of updates. When I next booted up I had a second kernel (2.6.32.9-70) and the usual other option for my XP dual boot (which still works!).Selecting either kernel leads to the Fedora logo on a blue screen and then a black screen with a small underscore cursor in the top left and no other text. This is not a command line or a text editor but it simply displays key depressions - the alpha/numeric section of the keyboard in upper and lower case as normal and then the function keys and numeric key pad as control codes commencing with As both kernels yield the same behaviour, am I right in assuming that it is one of the program updates that is causing the problem? The only way I have found to get out of this screen is ctrl.alt.del which gives a short list of programs being stopped and then the machine reboots. I don't know how to pause this screen to get the details before they disappear.I have been through loads of stuff on this forum but nothing seems to fit. From the command line terminal off the boot options screen I tried su -c yum clean all and also yum clean all but all I get from Grub is error 27 unrecognised command.
As you can tell I'm a complete beginner, but I am willing to learn. The thing is I don't know where to go from here. All I want for now is to get back to the Gnome environment I can handle, then I can explore the command line at my pace instead of being thrown in at the deep end!

I'm running Fedora 13 64 bit. Everything has worked fine, until today. The latest updates killed the video.
As the bar at the bottom of the screen starts to go across and say Fedora 13 the whole bar starts to flash then goes solid white. No errors or nothing, just a black screen. What causes this?
Nvidia drivers are installed. Maybe it's them. I've had trouble with video after updates with the last 4 versions of Fedora.
How to fix this mess?

After I upgraded F11 to F12 on an x86_64, the new system boots and the daemons come up, then the screen goes black and the computer restarts. But then it won't boot at all. It just keeps restarting.It could be a monitor driver problem. The one time I managed to press "I" fast enough to bring GRUB up, I tried adding "nomodeset". Nothing changed. The monitor is an HP 2009m, so it should not need "nomodeset" anyway. Xfree86.cf has not changed from F11 to F12.
I have a full DVD, so I can bring up Rescue Mode. I had hoped to find clues in (/mnt/sysimage)/var/log/messages, but nothing is being written to it. Once after I rebooted off the hard disk from Rescue Mode, I witnessed a long SElinux conversion. That disquiets me. But disabling SElinux does not solve the problem either.Can anyone suggest some kernel options that might overcome this problem? I shrink from reinstalling F11 from scratch and having to restore all my files from my backup system!P.S. I just found in my personal X11 log a message to the effect that /usr/lib64/dvi/nouveau_dri.so is missing. So it is; the directory has 12 drivers and not this one. If I remember right, "nouveau" often figures in trouble reports.P.P.S. As myself in Rescue Mode I can use xinit to bring X up! But it has only a vanilla text window and no mouse cursor, so I cannot use it or get out of it.

I have done three times clean install for this and still i can't find what causes it.
When i do my clean install and configure my installation, after reboot i can login.
I see the login splash and then, i see a black screen and the only thing i can do is open applications with ALT+F2 command and change TTYS to login as root and i can move my mouse pointer. When i startx with root everything works awesome... Probably i changed something i musn't... Can the option "start everytime with new session" cause it, if yes how can i fix it and if not what can i do?

I turned on my Acer laptop and during bootup it seemed normal. After it passed the blue Acer logo, all I could see is a black screen and a black cursor outlined in white in the shape of an X. Thinking it would be a one time thing, I turned it off again.it still was a black screen.

I use xterm with a particular font size and type. But every time I start xterm I have to give them in arguments
Code:
xterm -fa terminus -fs 12
Is there some configuration file where I can out the above parameters and xterm will pick them itself. But I don't want these properties to be set globally. Every user should be able to set it for himself. I have searched all the hidden folders and rc files in my home folder, but didn't find anyone related to xterm. What should I do? Similarly every time I start screen, I have to issue
Quote:
:caption always
:caption string %w
Can I make it automatic by editing some configuration file? Is there any way through which every xterm I start will have a screen session already open in it?

I usually have several xterms open, with each one running a different gnu screen session. It would be useful if--at a glance--I could see the session name in the xterm title bar. That way I would be able to quickly tell which screen sessions are running in which xterms. This would be very useful when alt-tabbing.
I know that there are termcap, terminfo, and termcapinfo commands available, but I don't know how to use these. I also know that there's an $STY environment variable that stores the session name. Also, I do not want to lose my current "hardstatus alwayslastline" bar. It seems like this should be independent from the xterm title, anyways.

I cannot access xterm or an tty using ctrl alt fn getting just a blank screen. Even in booting to repair mode or logging into Xterm, I get the same blank screen.
Lucid with nVidia X at 1900 x 1200 - Had this setup for the last year so Karmic and Jaunty had no issues with xterm. Needing to resolve this to be able to load nVidia drivers.

I am running Fedora 10 on a Gateway Machine. I tried to install the corresponding drivers for acceleration but it seems to have broken the display. After the loading splash screen, the screen goes black and does not respond to anything. I did manage to see the Grub boot loader by pressing 3 a number of times while booting the machine. Any ideas for how to revert the computer to its normal display so i can try again at getting these drivers working. It is a tad bit annoying not having a display but hell, this distro is already as far as I can see 10x as good as Ubuntu.

I am trying to install Fedora10 on a eeeBox, where I understand the graphic card is highly irregular. After the initial loading (the white/blue ASCII-art bar in the bottom) I get a black screen and that's all.If I Ctrl-Alt-F2 to a text screen and, as advised, do "init 3" and then "Xorg -configure" and restart the server with the new config - the same happens. Just a blank screen..

I just did an update of my Fedora 11 machine, and it required a restart. After restart it will not try to boot up or even show a splash screen. The only thing I see is a black screen with a flashing white cursor.Any ideas on what I can check so I can boot up into Linux again.

I just updated from FC 10 to FC 12 via install/upgrade disk, and when re-booted the screen is then black (at the point that it should display logins). I think it may be due to nvidia driver in FC 10 not being upgraded, because I think I compiled it from nvidia rather from yum install. Anybody else have this problem? BTW, it is a dual boot with Win XP, but has never caused a similar problem before.

yesterday I updated the system, and that involved kernel 2.6.34.6-47.fc13.x86_64. After rebooting, the progress bar goes fine, but when finished the screen flickers a little and goes black. I can't switch to other terminals via Ctrl + Alt + Fx, so I'm using remote access via ssh. I thought it could be nvidia issue, so I updated kmod modules with rpmfusion-nonfree-updates-testing, and when booting nothing complains, but I'm still getting black screen. Xorg log doesn't seems to complain (no errors (EE)).

Running Fedora 14, and when I wake the computer after not using it for a few hours I get a black screen with only the mouse pointer visible. This can sometimes be for a minute or up to 5 or 10 minutes, I'm not quite sure what the issue is. I have the screen saver set to blank screen, and I have the computer set to never go into sleep mode, however the display turns off. I just tested it out with the screen saver only activated and it wakes fine, and then set it to turn the display off after 5 minutes, and it wakes up fine if I try then. The issue is when it has been idle for the night or longer. I am running this machine through a KVM, so I'm not sure if that may have something to do with it. You can see from the output here that the mouse seems to be getting discovered all over every time I switch back to this machine.
[Code].....
This isn't a major issue, but it is very annoying if I want to switch over to this machine to get a few things done and switch back. Also, if I am waiting at the blank screen with the mouse, I can still press ctrl + F2 to access the terminal immediately, so the computer is functional but the GUI seems to be delayed in coming back.
