Ubuntu :: GDM Flickers In A Loop?
Aug 9, 2010I have received the ZaReason Teo netbook I have bought, all specs are here:I have had it for 3 days now and haven't really played around with it very much: I have installed a few apps (skype, synergy, dropbox, texlive) and I've been basically getting acquainted, and I'm generally satisfied. A couple of hours ago I came back from the office, turned on the computer again and.. gnome started to flicker in an impossible loop! In one second, it will go completely white, then I'll see the purple Ubuntu background, then the application bar on the top and then white again. I see for a tenth of a second two suspicious arrows in the top left corner.
I have taken pics and made a sequence of the loop to help you guys understand:this happens immediately after login. when it loads, as in when you get "Ubuntu" and the 5 bullet points below, it doesn't flicker.While the screen loops in the sequence, i can open a terminal (using Gnome DO) and do stuff. I have tried to stop GDM, using "sudo /etc/init.d/gdm stop"What I then get is a command line interface where I can type something, but if I press ENTER nothing happens, it just goes to the next line. To restart the thing I need to press the power button off and on again. Here's the image of where I get. When I restart, it starts to loop again. I don't know what to do. While it loops I can enter commands in a terminal (thanks Gnome DO). I removed synergy but it didn't help either. As per now, it's really difficult and slow to interact with the machine, this really make it useless for anything I'd like to do with it.

The wallpaper loads, the screen blinks white and then it loads the wallpaper again... then a white screen, then the wallpaper.I've tried to bring up the terminal and can't do that. I've also rebooted in recovery mode which didn't help.I'm at a loss. I'm on a windoze machine now since I can't get on my netbook.

View 9 Replies View RelatedUbuntu Installation :: 9.10 Stuck In Loop As No Net Connection?
Jan 22, 2010I haven't come across this bit of 'elitism' before but it seems with this install one MUST have a working net connection. Why is this? How do people without net at all get to install Karmic Koala?
I am using the alternate install from a USB stick (UNetbootin) and I have to use a separate USB WiFi dongle (not the Wifi built into this Thinkpad T43). The installer does not recognise the difference, so consequently it fails to find the dongle and gets stuck in a loop between 'Net access failed' and 'Searching for a local mirror' - I don't understand why it needs a mirror at this stage anyway as I downloaded the correct and complete .iso
Major catch22 for me as I am attempting a fresh install due to the upgrade from 9.04 to 9.10 having totally screwed up my system - no ALSA, App menu gone doo-lally, etc etc - far too much mess to sort out.
On top of that, the trackpoint button has stopped working altogether and no amount of Fn+F8 switching makes any difference. Hmm.
Edit: Trackpoint somehow got disabled in BIOS during above aborted install.
Ubuntu :: Evolution In A Loop Sending The Same Email / Fix This?
Feb 19, 2010Basically, I think my Internet crashed while sending an email via Evolution and now whenever I open Evolution, or try and receive any new email it just sits there sending this email - it reaches 100% so I can only assume it has actually sent the email.
There's a button to "Cancel the current mail operation" though it doesn't appear to be doing anything; the email is still being "sent" each time.
This would be pretty tedious for the guy I sent the email to.
Has anyone had similar issues and knows of a fix?

View 1 Replies View RelatedUbuntu Installation :: 10.04 Login Loop With VIA Video?
Jun 25, 2010I have a box built by a local shop (AMD Sempron 2400+, 1.? gig RAM). It used to have XP on it, but I replaced that with 9.10. I tried installing 10.04 from CD and encountered the login loop problem many others have experienced. I had it working once when I re-installed 9.10 and then ran the upgrade to 10.04. I got the login loop that had music up to the cymbal crash, which was clipped near the end. I tried the recommendation to switch to a command line terminal, log in, run sudo dpkg-reconfigure gdm, and then restart gdm. It worked, and I should have left well enough alone. However, I thought that it would be cleaner to install from the CD. Unfortunately, when I got to the login screen I only got a blank screen when trying <ctrl><alt><F1> (or <F2, etc). <ctrl><alt><F8> took me back to the login screen where I still encounter the login loop.
I also tried the recommendation to run the install with the F6 parameter nomodset selected. That resulted in loosing the music during the login loop, although I've discovered that sometimes it's simply because the sound is starting out muted.
Another recommendation was to drop into GRUB when first powering up. It took me a while, but I finally found out that one must hold down the shift key on power up to get to GRUB. While that did let me log in to a command line screen, running dpkg-reconfigure gdm did not work, this time. Neither did the idea of editing the GRUB command line to replace quiet splash with nomodeset.
I have read many posts on this forum talking about this problem as it applies to Nvidia or ATI graphics cards. Has anyone had any experience with the VIA video built into a motherboard? Running lshw -C Display while booted from the 9.10 CD says that I have a VIA KM400/KN400/P4M800 [S3 UniChrome] video system.
A recommendation from one of my local PLUG friends was to revert to an earlier video driver that works. Is this possible? Can I take the video driver from 9.10 and use it for 10.04? If so, how do I find it -- what's it called, where is it, what is the 10.04 driver called, and where is it, and can I just change the name of 9.10's driver (if it is different from 10.04's)? If it isn't obvious that I really don't know how this level of things work, let me confess that I don't.

Dec 28, 2010When I boot into Ubuntu, it goes to the log in screen. I can type in my password and then the screen flashes black and then the log-in screen comes back. If I boot into recovery mode, I can log in via terminal, but if I type startx it just brings up a black screen and a mouse cursor and that's it. Did GNOME get messed up? How would I fix it? I have an Ubuntu LiveCD that I can use, so if I have to install any packages or something, would I be able to download them in the livecd and just install them on my broken installation instead of having to figure out connecting to wifi in a terminal?

Jan 22, 2011I am having issues loading Ubuntu 10.10 from USB. I have a HP Compaq nx9110 laptop, p4 3.2 512ram etc with a dead hard drive. I would buy a new HDD but i cant really vouch spending $80Aus on a IDE 2.5 just to play with linux. Anyhow it seems to read the USB stick which was created following the directions on this site but when it attempts to load the Realtec LAN (i think) it seems to get stuck in a loop. I have attached a screen print of what i see, it hangs for a few seconds then starts over with the same writing. Anyone know what that means or how i can fix this so i can try 10.10?
View 2 Replies View RelatedUbuntu :: ScanJet 6200c Causes Boot-Loop
Feb 16, 2011I have a system which has been running 8.10 for two years (and am preparing to rebuild). Yesterday I thought to reboot it and am now stuck in a boot-loop getting the "not responding" x.xxxxxx error.
I made no changes prior to the reboot (just felt it was time) other than moving documents off the main drive onto a spare (preparing for the rebuild).
I have tried booting into several of the previous kernels and I ran memtest (flying colors). I keep getting the same error.
I have now built a 10.04 system for this machine. The old 8.10 drive seems to be in perfect order and I was able to pull various files from it.
I thought this would be the end of it but if I boot this new machine with my HP scanner attached via USB (any port) I get the boot-loop as in 8.10.
Again no changes were made to the 8.10 build prior to yesterday's reboot, and that scanner has been attached for more than two years (and working with fair reliability). I have had to alter its USB port or (inclusive) power-cycle it for Ubuntu to find it, but I had to do this when it was attached to an XP machine and so thought nothing of it.
Why has (presumably) the kernel driver suddenly crapped its pants?
Oh, and for the doubters I was able to boot into 10.04, open x-sane (which I prefer over Simple), locate the scanner (after power-cycling it), and scan an image. I just had to attach the scanner to the machine after the kernel loaded (at the login screen).
Ubuntu Installation :: Login Loop After Upgrade To 11.04?
Apr 28, 2011I just finished the upgrade of 10.10 to 11.04, restarted and now i can't login anymore, i'm stuck in an endless login loop.
1) Boot
2) Xorg starts
3) I see my user, login
4) Screen goes black like it's loading
5) Loop back to login
It's not a password issue, i can login in command line It's not a profile issue cause i tried creating a new user from the command line and it still loops. I looks briefly at the /var/log/... but i couldn't find anything relevant,respond ASAP this is my work PC.
I thought it would be simple since it's a very simple a relatively new machine (2months ago)

May 27, 2011I have a box running Ubuntu 11.04 (natty). I have never run memetest before. Then, randomly, when starting up today, it ran memtest. Because memtest86+ is on a loop, it doesn't stop unless you stop it. So I tried restarting the machine - no good. It simply starts memtest again and runs the same testing loop. I cannot find any setting in the BIOS to disable memtest. how I can stop/disable memtest so I can USE my computer??

Feb 8, 2010I'm running Ubuntu 9.10 in a dual boot alongside Windows vista on an HP DV6000 laptop.It's been running smoothly for months. No problems.Today, I was in Ubuntu, and the Update Manager asked me to update (ok) and then said it needed to restart. I hit the restart now button and the system started to shut down, but never fully shut down. It's in a kind of loop, trying to start up, but not going all the way, and then shuts down again.I did a hard reboot but still nothing - the same loop. I don't even see my HP startup screen, nor can I access the BIOS, much less Grub.I put in the Ubuntu startup CD and it tries to read from that at startup, but then fails and returns to the same loop.
View 1 Replies View RelatedUbuntu :: Reboot Loop On Dual Boot Netbook?
Mar 10, 2010I recently installed Netbook Remix(Karmic, I think) on my Samsung N130 netbook as a dual boot with Windows 7. It had been working fine, I'd had no problems switching OS and I had restarted my computer many times without issue.
Today, I was on Windows 7, set it to hibernate when I left the house as I sometimes do, and when I came back and turned my computer on, first it asked which system I wanted to load which it never does after hibernation. I selected Windows, and it took me to the Samsung Recovery Solution screen for some reason, and I closed that. It restarted the computer, and when it turned back on it said GRUB loading, and rebooted again, and keeps looping that whenever I turn it on.
I tried removing Ubuntu using GParted from a flash drive, but I'm still stuck in the loop, and it's gotten rather frustrating.
Ubuntu :: Caught In Login Screen Loop - Karmic 9.10
Mar 16, 2010I have a real issue and need urgent help. I am stuck in a login loop and have looked in several threads in order to find a solution for my issue. I am relatively new to Ubuntu/Linux and do not really know my way around especially when it comes to command prompt. Thus I need someone with patience and who can guide me step by step in order to get to the bottom of the issue and to fix it.
The issue started all of a sudden, no particular reason. I only uninstalled evolution before and then rebooted. The shutting down process got stuck forever and I turn off the PC by holding the power button. Then I attempted to start, the PC boots to the login screen and I select my name and enter the correct password as usual. Then the screen changes for a split of a second to the back command screen and I can see the word crypto or so. Then the screen returns to the login screen and this loops.
