I need to get gksu to run programs. The goal is to be logged in as user1 and run firefox or google-chrome with user2 's settings stored in their own home directory. I'm trying the following with no success:
Code:
user1@hostname:~$ su user2
Password:
user2@hostname:/home/user1$ google-chrome
No protocol specified
(google-chrome:17144): Gtk-WARNING **: cannot open display: :2.0
Code:
user2@hostname:/home/user1$ firefox
No protocol specified
No protocol specified
Error: cannot open display: :2.0
Code:
user2@hostname:/home/user1$ gedit
No protocol specified
(gedit:17162): Gtk-WARNING **: cannot open display: :2.0
When I become root and try to run gedit, I get the error:
No protocol specified
(gedit:219: Gtk-WARNING **: cannot open display: :0.0
This does not happen from my user profile....xhost + actually solves the issue....so I guess I just need to add the host root to the list of hosts allowed to access the x server...
I was running Ubuntu 10.10 Maverick with no big problems till last 3 days ago.
The update manager checked some updates to install and after installing them, I had no graphic desktop any more. Only the command line.
I tried to recover it by starting the X again.
Code:
But did not worked
So I've tried to install the nVidia driver again. I looked at nVidia Linux drivers site for how to do it and Ubuntu documentation and when I tried to
Code:
I just could not use gedit. It cannot open display. I googled for three days but could not solve it. I found some similar answers here at LQ but none was similar to my situation or worked even when I tried.
I am still learning the ropes on Ubuntu server. I am trying to set up samba, but when I use the "gedit" command, I get this error: GTK-WARNING **: cannot open display I had installed the gedit command by using apt-get and aptitude, but still no luck. I am using virtualbox to test Ubuntu Server 9.10.
For example, the gparted application menu item doesn't work; using it means that there is almost no filesystem support. The only way to get it to work is to open a terminal, run 'su -', and then open it from there.As another example, I tried creating a nautilus script to open files as root with a command like this:
Code:
for uri in $NAUTILUS_SCRIPT_SELECTED_URIS; do gnomesu -c "gnome-open '$uri'" done
When I try using it, it just fails. Typing out the command in the terminal gives this (tested on a text file):
Code:
No protocol specified (gedit:13672): Gtk-WARNING **: cannot open display: :0
I'm pretty sure the problem is that it's granting privileges, but not using the full root environment, or something along those lines.
I've been searching for a permanent solution for some time now, but the threads containing the same error message never seem to be about the same issue.I want to:I'm not trying anything fancy, all I want to do is open a write-protected file with gedit as root, like so:
Code:
# sudo gedit /usr/bin/deadbeef
..but every time I try, no matter the file, I get this error message:
Code:
(gedit: [process #] ): Gtk-WARNING **: cannot open display
I already know: I can circumvent this by going:
Code:
# xhost +local:root # sudo su # export DISPLAY=:0.0
I'm trying to install Fedora10 on my new desktop. It has Windows 7 beta on it and Vista. It starts up fine and I select install. For some reason my wired usb keyboard will not respond unless I press the caps lock button while it loads the begging. (I don't know if another button will work, ive only used the caps button since i can see the light come on) once it loads i skip the disk check and anaconda runs, i get the warning (mini-wm:1462): Gtk-WARNING **: cannot open display: :1 .

planning to upgrade to the next LTS version i.e. 10.04. Have already applied all the updates and got the system up-to-date prior to upgrading. But when the upgrade starts I get the following message: Upgrading may reduce desktop effects and performance in games and other graphically intensive programs.This computer is currently using the AMD 'fglrx' graphics driver. No version of this driver is available that works with your hardware in Ubuntu 10.04 LTS.
Do you want to continue ?Obviously, I clicked on NO and got out.What gives ? How come an upgrade is supposed to DEGRADE performance ? What kind of upgrade is that ? Also what is the implication for me ? Will I have to happy with 8.04 forever ?The machine in question is a Toshiba Satellite A100. I use GIMP quite a bit on it, so problems with graphics intensive applications is kind of worrying.What am I supposed to do ?? Upgrade anyway or stick with 8.04 ?
I have the following scenario that doesn't seem to work normally. I have a windows 7 pc from which I am using putty to connect to my other linux servers (all running redhat 5 and 6). So here is the scenario that works and one that does not work. And I'm trying to figure out the one that does not work. Scenario that works:
From windows 7 (putty) I ssh into Linux_Server_1. echo $DISPLAY localhost:10.0
I run xclock and I see it pop up on my windows 7 pc. I am using xming on windows 7 to help me populate the display from linux to windows. One that does not work:
From windows 7 (putty) I ssh into Linux_Server_1. Then from Linux_Server_1 I ssh into Linux_Server_2. echo $DISPLAY <no output>
I try to setup $DISPLAY with localhost:10.0 or 0.0 or even my windows 7 pc ip address:0.0 ....etc Then when I try to run xclock I doesn't work.
I get these error messages: Error: Can't open display: <ip of display>
Also as a side note all our Linux servers are sitting on one subnet. My pc is sitting on another subnet. I use vpn to connect to the subnet where the servers sit from my pc.
Just installed F15, was everything fine, but then gnome got away, from terminal I have<gnome-session:1951): Warning can't start display message.Before that I put in config file one extra line to start tint2 like <sleep 3 && tint2.Not sure was it the reason?
I installed Open Office 4 on Debian 8 but when I run the program I get this error message.
root@localhost:/home/paul# openoffice4 No protocol specified No protocol specified /opt/openoffice4/program/soffice.bin X11 error: Can't open display: Set DISPLAY environment variable, use -display option or check permissions of your X-Server (See "man X" resp. "man xhost" for details)
Open Office works fine when I run the command "startx" in the Konsole but so far I haven't been able to configure it.
We have a digital signage appliance built on SUSE 11.3 with a LAMP server that uses the flashplayer application to play a .swf file from localhost. It is a AOpen GP7A mini pc that has the nVidia drivers loaded. We have lots of customers that have been running the exact same system for over 6 months (we image the drive for each sale).
For some reason, my last customer is seeing the following problem shown below, and this linux configuration is way over my head. Everything else is working (local LAMP server is working, communicating with our production servers to get information works, etc). I have verified that it is screen 0 that is running (at least it shows with Ctrl-Alt-F7). I thought that it may have occurred because of updating the software with zypper up. I had the customer rebuild from the image being careful not to upgrade the software. The result was the same. The pc is a newer version compared to my bench pc, but there are multiple other customers running that same version just fine. So I am not sure if it is
The command is issued by a php script that is run in a root cron job. As I said, it works great on all other customer pc's including my bench system. I also tried to execute the command on a ssh terminal as the root user with the same result. I also upgraded my bench pc and it still worked properly.
The command being executed is sudo env DISPLAY=:0 XAUTHORITY=/home/svision/.Xauthority flashplayer http://localhost/flash/sign.swf &
the result (when run in terminal) is: No protocol specified (flashplayer:15077): Gtk-WARNING **: cannot open display: :0
I have configured an instance in AWS EC2. I am trying to set the display back so I can run x apps. I login using ssh -xy -i...
export DISPLAY=XXX.XXX.X.XXX:0.0 echo $DISPLAY to verify xhost + xhost: unable to open display "XXX.XXX.X.XXX:0.0"
I have commented out nolisten tcp as suggested HERE I have modified /etc/gdm/custom.conf as suggested HERE Actually, the last suggested modifying /etc/gdm/gdm.conf, but that file didn't exist, so I added the line: DisallowTCP=false to /etc/gdm/custom.conf I rebooted, and still I get: xhost: unable to open display "XXX.XXX.X.XXX:0.0"
I am currently running Suse 11.3. I continue to get the following error when logging into the KDE login manager with my user account
"Warning: Cannot open ConsoleKit session: Unable to open session. The name org.freedesktop.ConsoleKit was not provided by any .service files."
After acknowledging the error, it resets back to the login manager screen. If I login with root, I get the same message, but it continues on and logins into the session
I just isntalled LAMP using tasksel and have a problem. Whenever I try to access a page (aside from phpmyadmin, that works well), I get this error... Code: Warning: Unknown: failed to open stream: Permission denied in Unknown on line 0 Fatal error: Unknown: Failed opening required '/var/www/index.php' (include_path='.:/usr/share/php:/usr/share/pear') in Unknown on line 0
I have restarted the computer, restarted apache, etc and still nothing. When I first installed, phpmyadmin was inaccessible, so I ran some command in terminal which apparently created a symlink between phpmyadmin in the user/share dir to the /var/www dir, and curious if this is the problem. I have no clue how to remove this symlink if this is the case, and have phpmyadmin working now due to install using sudo apt-get install phpmyadmin.
