I just upgraded from 10.04 to 10.10.After the upgrade I can't open any GUI programs running as root.
Or using gksu I just get the password prompt and then nothing happens.Same thing if running from the System->Administration menu.This is the same for all programs, not just Synaptic.Any idea of how I can debug this issue?
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'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

However, "E233: cannot open display" error appears when starting gvim on ubuntu 8.04root shell.

Open Office works fine when I run the command "startx" in the Konsole but so far I haven't been able to configure it.
I tried to upgrade from Fedora 8 to Fedora 12, but after preupgrade got everything ready I rebooted. Anaconda searched for storage devices and then said "No upgrade root found". What can i do to continue the upgrade manually?

I upgraded ubuntu 9.10 from the update manager- it had a couple of problems, and now when I boot there's no display- I'm pretty sure it's just the graphics driver since it loads up and plays the login sound.I'm currently running off a CD version of 9.10 and when I chroot the drive with 10 and sudo apt-get upgrade it says there's some stuff that depend on fglrx, and that it's not there.There were proprietary drivers installed before the upgrade- Is there an easy way to just run with non-proprietary drivers? Or to install non-proprietary drivers to another drive?
(I don't really know what I'm doing, if I need to boot to recovery mode and do stuff could someone please tell me how to do that? The only info I can find is maybe possibly press Esc during the os boot and that doesn't seem to work for me)
I upgraded my HP Elitebook 6930p from 9.04 to 9.10. When X starts the display shows random lines. I can boot into "recover" mode from GRUB and get the command prompt. 9.04 worked fine so I'm pretty sure it's not the video card. The video card is ATI Radeon HD 3400.
View 4 Replies View RelatedI have a problem since an update some weeks ago but I cannot remember which one, because I thought it would get fixed so I didn't revert back.The display shakes very often depending on the type of window displayed and I think it has to do with the hardware driver (nvidia 185 restricted). Was there an update not long ago?
You can look at the problem there:http://www.......com/watch?v=Es0CVNmXGJ8.I had to record it with an external camera because using GTK-recordMyDesktop the recording is flawless.As you can see sometimes it's almost unusable.It has nothing to do with compiz or emerald or awn or any effect, because even with everything turned off I have the same problem.
I used Ubuntu 9 (Karmic Koala) for some time with no problems. When I upgraded to Ubuntu 10 (Lucid Lynx) I ran into graphics issues.After I log in, the screen scrambles (a purple/green mess)--impossible to decipher anything, although I can get out by marking the spot on the screen to click for a restart, so Linux is working behind the scenes.If I start in recovery mode with basic graphics, I have no problems at all (other than limited functionality). If I start the old 2.6.31-22 kernel, I see a bunch of "unmountable" errors in the startup script, but I can use Linux normally with no apparent problems. I'm running an IBM ThinkPad A30 with ATI Mobility graphics. Just to reiterate, the screen looks fine until I log in, at which point it goes bonkers. I've tried lowering the resolution, to no avail. I'm not running any proprietary drivers. What do I need to change in order to fix this?

View 1 Replies View Relatedi have a large data file for gnucash of several years in age. when i did the upgrade, gnucash starts and loads, and the main account appears to load, but there is nothing displayed. just an empty gray space where the alternating colors of the ledger should be.the account listing loads, and i can view other smaller accounts just fine. but the main ledger does not display. however, if i click on some areas of the screen, it will display what i assume is the underlying text in the bottom status bar.
and when a window or some other graphic element 'over writes' any area, some remnants of the former image remain.
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.
I did search for this but could not easily find the answer I wanted. When I use update manager in 10.04 to upgrade to 10.10 I get an error that there is not enough free disk space. It seems the upgrade uses 19.9M and I only have 16M free from the 100M on my /boot. I am not sure if it is related but I have dual boot. And when rebooting, I have a lot more than just boot into windows or boot into ubuntu. The list shows something live five different linux boot options (ten if you count the recovery modes). It seems that there are five different 2.6.32 - xx - generic options. Are these taking up space and how do I remove the unneeded ones?If I should repartition /boot how big should I make it so this does not occur the next time? Here is the output from df -h

gedit has not been able to detect the character coding.Please check that you are not trying to open a binary file.Select a character coding from the menu and try again.If I open OpenOffice first and then the document it works fine. If I use the shortcut directly, it won't open.Not overly impressed with 9.10 so far; things seem much slower, and it's certainly not as simple to find things as the old layout was.
View 4 Replies View RelatedLast night I upgraded to 10.10 RC, and everything went smooth. A lot of problems were resolved in the upgrade, but unfortunately I got two new problems.1. No Sounds at all. My speakers hum, and I can control the level of the hum/mute with Kmix, but no sounds makes it through. So Kmix is controlling the hardware, but somewhere the sounds isn't making it there.2. No system settings. The system settings panel appears in the app tray when I run it, but after a minute of thinking (and not opening) it disappears.

View 1 Replies View RelatedI had 9.10 installed on my IBM Lenovo Thinkpad, x301. I was performing updates as normal, and chose the Upgrade button to upgrade me to 10.04. Everything started fine, but upon reboot, no bueno, Kernel Panic!
The exact message was "Kernel Panic ubuntu - not synching VFS Unable to mount root fs".
I thought this was a grub issue. Since grub2 now is installed... But it was not. I think it ended up being a problem with some of my configuration files.
I have three kernels I tried:
1. 2.6.32-22
2. 2.6.31-21
3. 2.6.31-20
The first threw me into the kernel panic.
The second would hang on "init crypto disks"
The third would hang on "checking battery state"
I noticed (from reading another thread) that while these are loading up that you can click on alt-ctl-F1 thru F6 and get prompt. (I also had my home directory encrypted, thought that was part of the problem, but it wasnt).
Once I get passed the loging, I am able to poke around. I tried manually start Gnome via "sudo service gdm start", but it failed. Said it was missing a configuration file. Then I tried on "sudo dpkg-reconfigure gdm" and it would not work. Saying some configuration files are missing or broken. It also said something about dpkg --configure -a, I am assuming this configures everything...
So I tried "sudo dpkg --configure -a" And selected 'y' to every option. Which basically installs the package creators default settings, and viola! Works.
Just wanted to share that knowledge for the other stuck in the upgrade hell.
Normally I would just copy my files off and reinstall, but it was encrypted... Another headache. I guess good in case someone stole my laptop.
Remember try to "sudo dpkg --config -a"
Since upgrading to Ubuntu 10.04, my Open Office documents take ages to open. Also, the system does not open pdf documents. Both these problems arose immediately after the upgrade. How do I go about sorting these bugs out.
View 9 Replies View RelatedYesterday I tried upgrading from 10.04 to 10.10 using the upgrade manager. About half way through, my computer froze up and the only thing I could do was reboot my computer. It had already finished downloading all the upgrades and the computer froze while it was trying to install the upgrades. When I boot my computer and the Grub screen appears, I chose the Ubuntu OS (I have a dual boot system of Ubuntu and Windows XP). When it goes to boot Ubuntu, it gives me a blank screen and then a box in the right hand corner that says this:
"Install problem! The configuration defaults for GNOME Power Manager have not been installed correctly. Please contact your computer administrator."
Then the screen remains blank. No cursor, no mouse pointer, nothing. I have researched this error message and it is either caused by not having any free space on my hard drive or that the upgrade packages weren't installed properly. In my case, it could be both. It is definitely the packages not be installed properly but I don't know how to find out if there is no free space on the hard drive partition for Ubuntu. Some of the solutions are to use the following commands in the terminal:
sudo apt-get clean
sudo dpkg --configure -a
sudo apt-get --reinstall install ubuntu-desktop
The last command might cause me to lose previous settings, so that would be a last resort if the first two commands don't work. So my main issue is that I cannot open a terminal. My computer is set up to automatically log in. When my computer boots, I have the Grub screen which allows me to choose the Ubuntu OS, Ubuntu in recovery mode or Windows Xp. However, when I choose Ubuntu in recovery mode and select "c" for the command line, it does not recognize the "sudo" command. Same when I choose the command line in the regular Ubuntu OS. When I type "sudo apt-get clean" (without quotes), it says "Sudo command not found." I cannot find the command lines that would be the equivalent of a "sudo" command to use in recovery mode.
If you hit the TAB key while in the command line of recovery mode, if gives a list of commands but I don't see a way to open up a terminal window. For example, when I type terminal_input, it just says, Active: Console, Available: usb_keyboard." I have also tried selecting the Ubuntu OS, waiting for it to boot and then hitting Ctrl+Alt+F1 but it does not give me a log in screen. I have tried Ctrl+Alt+F2 and Ctrl+Alt+F7 and neither of those give me a log in screen either. It is just a blank screen. No cursor or mouse pointer is visible. All I want is the ability to open up the terminal so I can run "sudo apt-get clean" and "sudo dpkg --configure -a".
I was using the latest stable release of Debian, dual-booted alongside Windows Vista, with the GNOME desktop, installed via netinst, trying to build and install a library that I knew and trusted, when suddenly I couldn't open the Root Terminal. I clicked the link (in Applications->Accessories (I think, whatever the top one is)->Root Terminal), and in the taskbar I saw an item that said "Starting Root Terminal". A few seconds later, that went away, but the terminal still wasn't open. I tried the regular user terminal, to see the same thing happen. Unsure of what was happening, I tried restarting my computer, since that's always the first step you should take in computer problems.
When I restarted, GNOME wouldn't start. The screen would flash a bit for a few seconds, then a dialog box would appear over a background of static that said "The greeter application is crashing. Attempting another one...".t would then go back to the DOS-style kernel, wait a second, and then the same thing would happen. After several of that, I would get a blue screen which said something to the effect of "It has been detected that the desktop environment has crashed six times in the past 30 seconds.
Waiting two minutes before trying again." When it did that, I tried logging in as root to assess the problem. I gave it the correct password, but it said that it was an incorrect login. After several tries (to ensure I didn't mistype the password), I logged in as myself. Same problem. I tried the su command, with the correct password, and it said it couldn't authorise it.
After a lengthy conversation with a friend of mine who was very good with computers, he basically summarised that he had no clue, but that his best guess would be a virus. Upon running the Linux installer, I found the Repair option. Not being particularly familiar with Linux, I used it simply to backup my important files onto a flash drive. I then tried running the Install option, in an attempt to simply write over my existing Linux and make it new again. The installer, however, consistently froze up when trying to start the partitioner, on the "Checking disks..." stage. I figured it was a problem with my partition. In my naivete, I simply used the Windows tools to clear that partition... It destroyed GRUB too, so I couldn't run any OS. I figured my computer was pretty well screwed, and at that point just decided to bring it into the shop and have them completely wipe it.
my computer was backed up onto an external hard driven I brought it back, I reinstalled Windows. Upon restart, it said that it was still looking for GRUB, which made no sense to me. After messing around with it a bit, I decided to just reinstall Linux too. To my lack of surprise, that fixed the problem. Both OS' now ran just fine. The first thing I did on Debian was to install the Clam Anti-Virus, which I understood to be one of the best Linux anti-viruses. However, within about 10 hours, got the same problem as originally. I wasn't doing any of the same things, and between the lack of consistency in activities and the fact that I had an anti-virus running,figured it wasn't a virus. Not knowing what to do, I just left it and have been using Windows since.
I am running Ubuntu 10.10. After the most recent major upgrade I started getting the above message when booting with the default kernel, Linux 2.6.35.30 Generic. But if I drop back to Linux 2.6.35.28 Generic then everything works fine. I have plenty of free memory and none of the previous posts seem to apply to this problem. I downloaded and ran the boot info script and here are the results:

I've upgraded to fedora12 from fedora11 using preupgrade.
The process was successfull till the first boot, where I got above error message.
I am attempting to upgrade Fedora 12 to 13. I get an error screen that said root could not be found. Four options are given. Not sure exactly their wording, but two appear to allow you to cancel the other two warn that if you reinitialize you will wipe out all data.
I have a Vista partition and a Fedora partition. I've added the vista ntfs partition to fstab with no help. All of the partition use the long UUID form. I added the root location (root (hd0,5) to the upgrade menu item in grub.conf and that didn't work either.
I'm reluctant to proceed for fear of initializing the entire drive. I could live with installing Fedora 13 over the existing partitions.
I'm a long time Linux user. Finally got around to upgrading my Fedora 11 system to Fedora 12 by using the 'preupgrade' tool. The upgrade appeared to go well (downloaded packages, rebooted into installer, etc). However, now that the upgrade is complete, I'm unable to boot my system.
Here's my configuration:
/dev/sda (80Gb)
200Mb /boot partition (ext3)
52Gb / partition (ext4 - managed as logical volume)
2Gb swap partition (managed as logical volume)
20Gb /spare partition (ext3 - managed as logical volume) .....
All worked fine under Fedora 11 for the last few months. Grub now presents me with 'Fedora' and 'Windows XP' boot options. The /boot/grub/menu.lst file is essentially the same as it was for Fedora 11, except for the different kernel versions, etc. The boot sequence shows the Fedora bubble (??) and gets about 80% full when the screen goes black and the message displayed is:
No root device found
Boot has failed, sleeping forever
If I boot Windows, all works fine.
Am able to boot using a SystemRescueCD disk. The disks all look okay and I can mount/modify all partitions, etc. The grub menu.lst file read as follows (sorry, typed in, not copied):
default=0
timeout=10
splashimage=(hd0,0)/grub/splash.xpm.gz
hiddenmenu
title Fedora (2.6.32.11-99.fc12.i686.PAE)
root (hd0,0) .....
I've just upgraded to 9.10 and found that the menus in Open Office are unintelligible gray blocks.
Many apps are fine, like Firefox, gimp and thunderbird, but OO is scrogged up. I also noticed that Quanta has unintelligible sub menus although the top level menus are readable. The lists of files in Quanta are gray blocks, but if you click on a folder, the file names appear, then chaneg back to gray blocks if you click the folder again. Tried reinstalling Quanta but no success.
