Ubuntu :: Have To Restart Gdm After Boot To Get Third Monitor Working?
May 2, 2010
I have a three monitor set-up under 9.10, the monitors are connected to a pair of nvida 512MB GT240s, two on one, one on the other. After booting, I get the logon screen but only two of my monitors have a picture; to get the third running I need to login and restart gdm within a terminal and then login again. I'm using the proprietary nvidia 185.18.36 drivers (which oddly report my cards as 1024MB GT230s), with Xinerama. My xorg is included below.

I'm running ubuntu 10.04 on a new pc I just bought. Every so often the monitor will just shut down and display a message: "no signal input". I'm sure the computer is still running though because the fan is still running and all lights etc. are still on. I've tried switching the monitor on and off and there is still no input signal, the only solution is to reboot the entire computer.

I've recently installed a second monitor and it's great having all that extra space.
However, Ubuntu 'loses' the new monitor after a restart and I have to go into System>Preferences>Display and get the second monitor re-enabled and put to the left of my existing monitor. Quick flicker and the second monitor is on.
I don't really want to have to do this every day so am I missing something so my second monitor is remembered?

I've just bought a new monitor - Viewsonic VA2213w and am trying to set it up with Lucid. The resolution required is 1920x1080 @ 60Hz. I have an NVidia GTS250 with the proprietary driver v195.36.24 installed. I can set the right resolution in the nvidia-settings app, but it will not survive a restart. X always reverts to 1024x768. I have manually edited xorg.conf now to try to force the mode. The GDM login screen displays at the correct resolution, but on logging in X changes the resolution. Xorg.0.log shows the resolution being correctly set to 1920x1080 initially, then right at the end for some reason it is reset to 1024x768.
xorg.conf

I've just installed Ubuntu on my laptop. My laptop has an nVidia card so I'm forced to use the nVidia configuration tools. What I'd like to happen is for it to automatically start using my monitors if they're detected. OR, make a simple script that will enable the monitors without needing to restart X.

I have a mac book pro 5,3 with the nvidia gforce 9600m. After getting Ubuntu installed as a dual boot, I wish to use an external monitor while using Ubuntu. (it doesn't have the problem with OS-X) The external monitor is a samsung syncmaster 192 n. when I connect the other monitor and press 'detect display' both go grey creens(the external already is of course). My lapton screen will not recover until restart either. I need this monitor to run a numerical mesh 3d mesh creator that will not fit on my screen alone. Wouldnt be a problem if the creators were software engineers but the program window cannot rescale, and is beyond the resolution capabilities of my 15'' screen alone.

I just recently purchased a DELL PowerEdge 2850 and have tried installing CentOS 5.4 on it. After the install completes and it does a first boot I get the following error on the DELL console: PROC 1ERROR, PROC 2ERROR E07F0. The monitor remains black and the system hangs. Just out of curiosity I installed Fedora 11 on it to see if it was a hardware problem. Fedora installed and booted no problem. I rebooted with Fedora installed several times and left it running for 24 hours. Everything is working great. Is there something I am missing in the CentOS 5.4 install?
Below is the Hardware Config:
Dell PowerEdge 2850
PERC 4eDi RAID Controller
8GB PC-5300 ECC Memory
2 Intel Xeon CPU Dual Core 2.8GHz 800FSB 4MB Cache - SL8MA
ATI Radeon 7000 Video Card

I upgraded from Ubuntu 9.10 to 10.04. After the upgrade, mplayer no longer play a DVD.
I put the missing codecs, as described here: [url] Now DVD worked.
Also during the upgrade package libvdpau1 was disappeared, I restored it from the default repository. Then vdpau worked, but only after a reboot. After restarting gdm (select "Log Out" or sudo service gdm stop/start, or Ctrl + Alt + Backspace) an error:
After reboot everything works again.I updated libvdpau1 from repository [url], but it did not help, same error.
Video: nvidia 9600M GT
Notebook [url]
Driver set the default, 195.36.15-0ubuntu3, from the standard repositories.
In Karmic was 185, everything worked.
I noticed this feature, I do not know whether it is connected with subj:
Immediately after loading the gdm starts with the seventh console, ie when you exit the virtual console by Ctrl + Alt + F2 again to hit Ctrl + Alt + F7.
After you restart gdm is in the eighth console, Ctrl + Alt + F8.
If I run a guest session, it starts with the ninth console.
In the karmic like always with the seventh started.
When booting too strange things happen.
Ubuntu Karmic I installed with Alternate CD to an encrypted LVM.
I booting in text mode, ie without "quiet splash".
Booting reached requiring a password, when entering the password does not display an asterisk, after entering the password then continue normally.
After upgrading to Lucid booting lines are shown as a twisted, ladder when entering the password it displays asterisks and when I enter each character again displays prompt.
I did not like, and I again put the "quiet splash".

I've recently installed Ubuntu 10.10 and everything worked like a dream the first 10 days. Now I have to restart X to get my keyboard to work like it should. When I start the computer everything is fine until the login prompt where my password contains certain letters that don't work. To fix this I must use ctrl + alt + F1 and then start htop/top to find PID of X and kill it. This fixes the problem temporary but after next reboot I need to the same again...

I am running a headless home file server with ssh, samba, webmin and webgui for Transmission. It was all working fine on my lan until I tried to set ssh to listen on a different port (I read it was safer to do so if you wanted access from the internet). Now I cannot ssh into my server and as far I can tell using webmin the ssh process is no longer running and I cannot restart it. I have restored my unmodified sshd_config file. After restoring my original config file and rebooting I am back and working.

I did these steps to change my username: I like to directly edit /etc/passwd and /etc/groups
First open a terminal, become root
Code:
sudo -i
Now:
Code:
usermod -d /home/new -m old
sed -i -e 's_old_new_g' /etc/passwd
sed -i -e 's_old_new_g' /etc/group<-
sed -i -e 's_old_new_g' /etc/shadow
My computer shut down after I did the second step and now my password isn't working! I cannot open my home folder or get back to root!

I upgraded to the newest version of Ubuntu a few months ago, and ever since then, the ethernet connection to my router stops working when I restart the machine. It eventually comes back, but after varying amounts of time. Sometimes 20 minutes, sometimes 2 days.
Restarting the computer and cycled reboots of the router don't seem to have any beneficial effect, at least that I can detect.
The light for the slot on the router does not light up like it normally would, so it's almost like the OS doesn't even recognize the network card.
Ubuntu 10.4,64-bit. Dell XPS 410.

Today I updated my system, I noticed that KDE would be upgraded to 4.3. Upon restart of my computer my wireless didn't work (and still doesn't) and I cannot use the desktop effects anymore (probably the graphics driver). Is there any way I can fix those problems, or downgrade my system so everything just works? I'm using Fedora 11 KDE (64-bits). And I've kept a list of all updates. Ok, I figured that it was a different version of the kernel, the update set the other kernel to default. I'm back to 2.6.29.6-217.2.8.fc11.x86_64 and everything works.

After NFS mounting some system folders (i.e. lib, usr) of a slave cluster node to /lib & /usr located on the master cluster server I got into some problems: I forgot Ubuntu 10.04 was installed on this particular slave node, while the master node runs 9.10. Now, I am not able to unmount these folders using umount, or restart the system using shutdown, I get some error: " /lib/libblkid.so.1: version `BLKID_2.17' not found". Is there an alternative way to unmount these NFS shares, or to restart the system to undo the mounts? The systems are located elsewhere, so just physically restarting the system would not be the preferred option.

I successfully installed 1.4 last night. ran perfectly. Asked me to install the NVidia graphics driver. Not problem, still worked fine. Had to reboot, no problem worked just fine. Shut the machine down and two hours later the machine starts, goes through Bios, says booting OS, then restarts. just stays in this loop.I also installed virtualbox, which opened fine when tested. I did not add a new OS.I re-inserted the usb drive i did the original install from and it the install program loaded fine.Is there a way to role back to the last known good configuration?

I have a new Dell 3500 laptop with a dualboot Windows 7 and Kubuntu 10.04. Directly after installing Kubuntu the pc was able to restart without problems. However having shutdown the pc once and restart again it fails to boot in Kubuntu.
No error messages are shown, nothing at all. What happens after selecting Kubuntu in OS's, for a couple of seconds a bar ("-") flashes upper left corner of the screen. After that the screen goes entirely black (as if it were shut off).

I have a Toshiba Satellite A135 with a built in Atheros 802.11 b/g wireless card. It worked perfectly up until i upgraded from Fedora 12 to 13 but now it quits working and when i go to the terminal and type service network restart I get this:
[Nemesis@Nemesiss-paradise ~]$ su
Password:
[root@Nemesiss-paradise Nemesis]# service network restart
Shutting down interface eth0: [OK]
Shutting down interface wlan0: [OK]
Shutting down loopback interface: [OK]
Bringing up loopback interface: [OK]
Bringing up interface eth0: Error: Connection activation failed: Device not managed by NetworkManager [FAILED]
Bringing up interface wlan0: [OK]
[root@Nemesiss-paradise Nemesis]#
And I am not sure what to do, I can get the wireless working again if I completely shut my computer down and restart it. I am running gnome.

Whenever I start my PC, the information of 'First Boot device' in BIOS changes from hard disk to CD-Rom. It happens with new start, I mean, if I restart my computer after resetting First boot device to hard disk, then priority does not change. Just as I switch on computer, a black screen appears with the message:
CMOS - checksum error - defaults loaded
press F1 to continue, DEL to enter setup
Recently it used to happen, that PC was not reading my hard disk containing GRUB. I have 2 hard disks. I switched the power cables of two hard disks. After that, both hard disks were shown by BIOS but the above mentioned error started appearing. Also grub takes too much time to load. It takes almost 20 seconds. Earlier I was using 'Puppy Linux'. In that, Grub was loading in fraction of second.

I installed Lucid Beta a few days ago and was happy with the way everything worked. The system wanted an update on Thursday night, I installed it and then carried on using it for about an hour, it was then shutdown normally with no errors. On Friday morning it would not boot. I pressed the "on" button it came on, all the other lamps lit ie Caps and Num Lock, the battery light is on anyway, but the hard drive light is not flashing, it's as though it isn't being accessed, but I can hear it? There is no display on the screen. I'm running an Acer Aspire One. My initial thoughts are bios related, but I can't see how that would have changed, then I think maybe the Harddrive is knackered.

I had Ubuntu 10.04 on my 500GB Samsung drive. Today it suddenly stopped responding, not only X11 but the whole system (Ctrl + alt + f1 didn't worked either) so I had to force restart it. Since then, I can't boot it again - right after memory test and general motherboard splash, the white line cursor goes about 3 lines down of topline and stops there. After about 5 minutes there's still no GRUB menu. Finally I had reinstalled the system (which is not really much pain since my "home" was on other partition than the system, but it didn't helped - still the same. On the other hand, booting USB Live works perfectly fine (I'm using it right now). I have an access to all the partitions, all the data seems to be there, SMART utility says the hdd is healthy ..
Oh, and I tried reinstalling with grub-reinstall before, it said that the reinstallation went fine but didn't helped either

First off, i have ran 10.10 for the past 6 months without any problems. Then last week i decided to try 11.04. I installed using Wubi. Now the problem is the computer only freezes when I am using a web browser (firefox). it completely freezes where I can do nothing, so I will kill it with the power button. When i try to restart, not even the bios will boot up, just a blank screen with the num/caps lock key flashing.
But after trying to restart several times the bios and boot loader will eventually come up and will start up normally until the same thing happens. I decided to reinstall using wubi so when i tried to boot itno windows, the windows partition was corrupted. I fully restored windows and installed 11.04 with wubi again only to have the same freezing problems.
I will be trying 10.10 again and see if it just a 11.04 issue, but thought this problem should be out there if anyone else has a similar experience

I have a Dell desk top PC, running WinXP and Ubuntu 10.04 LTS with a Ge-Force FX 5200 video card. In trying to get both monitors to work properly I thought it would help to reinstall Nvidia binary X.Org driver V173. After I removed the driver I tried to restart the computer with Umbuntu, it hangs up at the Ubuntu logo. I can boot with the live disk, I also tried to reinstall the Nvidia driver But the machine still will not boot from the hard drive, it will boot into Win XP normally.hould I just reinstall Ubuntu or fix the problem I created? My skills working in Terminal are minimal

I have just finished the upgrade of the latest version and I'm at the point of my system restating.
My system automatically tried to restart but on the restart I got the 'terminal' view. It stopped when asking for my username (it never normally asks for this before the grub menu) and then password. I didn't get any further than that.
I now have on my screen (still in the terminal view before the grub menu)
"name@name-desktop:...$ "
I'm on my phone now so I don't actually have the symbol for before the dollar sign but your know what it is. The raised S on a 90 degree angle.
