I'm running 10.04 and when my screen locks I can't unlock it. I enter my password and it checks my password forever. This is a recent problem. I don't know what's causing it.

I have a Emachine el1200-05w AMD Athlon 64 2650e / 1.6 GHz NVIDIA GeForce 6150 SE 2.0 GB mem. and 160GB HDD
I had to fight to get it to install kept freezing and stopping. I finally got it installed. It runs fine and is fast. I like it alot and then after about 5 to 10 min. The screen locks up or will distort in multicolor stripes across the screen. I cant figure out whats going on!
I did just notice that the specs say it's a 64bit possessor and I'm running the 32bit ubuntu will that make a difference?
Still having problems with the locked black screen freezing a couple of minutes in. I've done everything anyone has recommended on the other threads but nothing and it is driving me crazy. Please, does anyone have any ideas? I tried to install xfce4 but of course, screen froze and went black before I could fully download the software! I've tried the nomodeset but can't save it before doing a reboot (then went via terminal as quick as I could on start up to edit grub, but then... yes, it fell over and froze before I could hit save). So I'm giving this a lot of time I really don't have... such a shame I upgraded, 9.10 was working so well... alternatively,

View 3 Replies View RelatedWhen I lock the computer, and move the mouse to unlock, the unlock screen is invisible and can't be seen. I can still type in my password and manage to unlock, but I can't visually see the screen, nor can anyone leave me a message while I'm gone. This only seems to affect GL screensavers.

View 1 Replies View RelatedI run into a new kind of problem with Ubuntu 10.4 LTS. The unlock screen dialog that asks for your password when resuming from the screensaver does not show up immediately. Moving the mouse, typing stuff. It does not seem to be a pure display problem, since typing the password does not seem to do the trick. After a while (about 15 seconds), it shows up, though.
View 1 Replies View RelatedRecently, ive been having this problem with ubuntu in which while im watching a movie and thus not doing anything else, everything locks up except for the sound (if i attempt to move mouse doens't work) and then it goes into the login screen. Previously, ubuntu would fade away into the login screen.
So is there any way to prevent ubuntu from going to the login screen if the user is not moving the mouse? non-fading login screen?
edit: oh and i also have this sometimes occuring problem where i type my password to login, it logs in, and then it immediately goes back to login screen. A second login works. probably not relevant
I am not sure exactly what is going on, but my ASUS UL30a (X32a) keeps locking up until I press a key, then it seems to resume for a while.
At first I thought it was just the mouse, but I noticed that the screen stops refreshing also. Hitting the space key (or any other key) brings the systme back to life (until it happens again).
It is a fresh install of Ubuntu 10.10, not much seems to be going on in the top list (compiz 1%, xorg 0.5%)
I am looking for ways to try and diagnose the problem (if not fix it )
using update manager, i allowed my karmic desktop at work to begin the upgrade process to lucid on friday afternoon... i ran out of time, and headed home for the weekend. somewhere along the process, the screen locked. after arriving back at work this morning, i cannot unlock the screen, or even switch users. other threads in this forum seem to indicate that i should've aborted the upgrade, but... i didn't know enough to anticipate problems, and i guess i assumed that given the lengthy estimate to complete the upgrade, i could just pickup the process again on monday.
in any case, cycling the power didn't help, so i downloaded the iso, and have booted to the 10.04 'trial'. i was hoping somebody could help guide me through resetting a password on the on-disk os from the live cd... i'm ok with reinstalling if i can preserve my account's configs & prefs.
This has happened in natty more than once. Once the screen gets locked after long periods of no keyboard/mouse activity (all ok for short periods of time), I don't even get back the familiar unlock screen with password.I get a blank screen and then Io a ctrl-alt-f7Is this a known issue in natty? Or is this a gnome bug
View 2 Replies View RelatedWhen I unlock the screen, I'm presented with an opaque dialogue (white box), regardless of whether I have a screen-saver or not.

View 1 Replies View RelatedI just installed 10.04.2 Desktop. Full install, reformatted all partitions. Hardware: Dell Optiplex GX200 with Dell 781p monitor Dell mouse and kybd.
All appeared to install well and as expected.
The computer has locked up 4 times, now. Whenever I attempt to use the mouse to drag a window to a different place on the desktop the monitor goes half black (bottom half of screen) and I loose the ability to use the mouse or keyboard to provide input. The only recourse is to shut it down hard and boot up again.
I've been using Ubuntu for about a year or so and have never had any problems installing it up until now.
I can boot from live CD for 9.10, but if at any point I attempt to install it to my hardrive, it either locks up or the screen goes black. Sometimes I'm able to start the installer, but the screen will go blank. The most progress I've been able to make on the install was up to 98% before it locked up, every other time I've gotten a blank screen or a lock up around 40-60%. After a hard reboot I get an error that reads "DISK BOOT FAILURE. INSERT SYSTEM DISK AND PRESS ENTER"
This problem doesn't only occur with 9.10, but with every other linux distro I've tried on it. My first attempt was with Ubuntu Studio, but I got similar errors. I've searched literally for hours and have found nary a solution that even comes close to solving my problem. using HP Pavilion a404x desktop
I just got a wireless dongle because in my house wired is not possible, but now I am getting problems. The dongle is a tp-link that turned out to be plug&play (unlike windows) and seems to work perfectly, except when the screen locks. I have tried to download overnight several times and it seems like a few minutes after the screensaver comes on or after I lock the screen, the connection is dropped. It works completely fine normally. So what changes when Ubuntu (its maverick with all updates) locks the screen? Also, when I log back in, I have to unplug the dongle and plug it back in to get it to connect again.
This is really REALLY annoying, enough to make me switch back to windows if I can only download while I'm looking at the screen.
I have a very strange problem since I turned to kubuntu 10.4. Often, after some heavy working, my laptop works very slowly and suddenly when loading something, it locks and white lines turns all over the screen, just like curtains. Linux jumps out of KDE and logs in automatically. That's very anoying since all my work is lost and it turns back to the previously saved session.
Also, often when I boot, the load screen is also mmissed up with those white lines. The only thing I can do then is to reboot.
I tried to re-install kubuntu (in first instance, i upgraded in kpackage, then i re-installed with formatting the root en swap partitions).
I don't know how to solve it. Only thing that seems reasonable now is to downgrade, since i didn't have this problem on 9.10 (fyi: I have a dell inspiron 1501 with ATI Xpress 1150 256MB HyperMemory video card, formerly i had problems to have good graphic drivers for it on previeous versions of kubuntu (some 3d games didn't work), maybe this has someting to do with it?)
I have a Dell Latitude E5500. For some time I've been installing different distros on it to find which is best suited for my needs. I've tried Ubuntu, Kubuntu, Mandriva, openSuSE, Fedora, and several others. So far, openSuSE takes the cake in terms of what I need, speed, usability, etc. However, I have a soft spot for Fedora and I'm trying so hard to make things work, but I'm kind of at the end of the road unless you guys have some suggestions.
I was in the IRC chat for Fedora asking around, and one user was kind enough to point me in this direction, which made sense as to why I was having issues.

I was having mixed results, but I had also installed from a Fedora KDE LiveCD. I decided I'd try the full DVD release of Fedora 12 64 bit, so I installed it this evening.
To my disappointment, even the nomodeset parameter does nothing. I get to the blue screen where there's some kind of logo in the center that fills in with white. After it fills in, an F appears. That's where it stops. It just goes no further. Further adding to the confusion is the fact that the fix lists a kernel there, indicating (to me at least) that the kernel listed is when a fix was deployed. I have a newer kernel than that, and despite that I still have these issues.
So needless to say, I'm using my laptop as testing grounds to plop a different distro than Ubuntu on my laptop and 2 servers full time. I really want to make Fedora work, but at the same time I have to use what works for me. Not being able to boot and log in is kind of a big deal. :P
Is there anything I can do or try? I want to keep the OS's I run all the same, so if Fedora 12 bombs out on this laptop, it has no chance on the other servers I plan to run at work. So far openSuSE is running without a hitch but I'd really like to give Fedora 12 a chance....
I'm using SolydX, based on Debian Jessie. XScreensaver is installed and disabled, but it still locks my netbook screen after some minutes and suspend mode. Waking the netbook up brings XScreensaver login window. I'd like lightdm login window to appear instead.
View 3 Replies View RelatedAfter a recent "yum update", my laptop screen locks up during graphical boot. I use rhgb on the kernel line. The container on the screen fills up with charge and then the screen locks. I have to use the power button to reboot. If I press ESC when the boot splash appears (i.e., boot in text mode), it works.
If I set plymouth to "details" mode using
$ plymouth-set-default-theme details --rebuild-initrd
It boots up correctly. This is equivalent to a text boot screen. I doubt whether it is a video driver problem. I reinstalled the nvidia driver and it is working. I also reinstalled plymouth and plymouth-themes-*.
This is a bit complicated to discribe because I don't know the cause, but this problem has been happening for some time (over a few years and generations of kernals), with different Gnome distributions, including Ubuntu (and family) and Fedora. When using Gnome (and only Gnome), I frequently see the screen dim. At the same time, all processes will be locked up. This may happen for a second or two, or it make require a reboot. The mouse can usually move and the underlying program GUIs are still visible, it's just that one or more of the GUIs will be dimmed. This is usually most noticeable with a browser, but that may just be a coincidence.

Otherwise, I get to the login screen and have just enough time to start typing in my password before the entire system hangs hard - no mouse, no keyboard, can't even get to a terminal, nothing. Have to hard power off the machine.
It seems to be a problem with the wireless card trying to initialize, but there doesn't seem to be a bios option to disable wireless on this laptop, so I'm a bit at a loss as to how to fix this problem. By the way, wireless works fine if I boot up with a cable connected - I can see all the wireless access points in my area no problem. I just can't boot without a wired connection, which makes my laptop more or less useless when I'm away from home with it.
I spent some time on this issue and I just wanted to share a resolution that was difficult to find (at least for me).Yum was working fine for me for a long time on my Fedora 12 installation x64, when suddenly it stopped during transaction checks. It didn't matter which package I was installing, or if I performed an update or anything. Always in the same place, and it always required a kill -9 to stop the process. Even with debugging turned on in yum (-d 10 -e 10 --rpmverbosity=10) it would not display an error...just hang during the transaction check. I tried the following to no avail:
Code:
# rm -f /var/lib/rpm/__db.*
# yum clean all
# rpm -v -v rebuilddb
Still, it would lock after the transaction test. The only thing that solved my issue was running:
Code:
# strace yum -y update This showed me that I had a stale NFS mount that was in a hung state. I tried umount but it just showed that the device was busy and would not unmount. The only way to fix it was to perform:
Code:
# umount -l /mnt/data which allowed the stale mount to be removed. Once that was cleaned up, everything worked. I struggled with this because there were no debugging messages, and I had no idea the transaction check would go through all of my mounted drives. However I just wanted others to know about this, because it was a rare issue, and I had trouble finding the solution.
I have a generic PC (VIA chipset, AMD 1.8 GHz, old NVIDIA card, etc) running Ubuntu 10.04 side-by-side with a Windows XP box. The Ubuntu box can see and mount some of the Windows disks via SAMBA. Recently, I had a little hardware problems with the Ubuntu box but cleaned the fans and reseated cards and things seemed better. Today the Ubuntu box rebooted and when it came back up I could log in OK but then the X11 GUI locked up in a continuous "Starting File Manager" loop. If I click anything the taskbars go away showing only a blank wallpaper screen then the taskbars return but but will recycle if I click on anything. I can reboot in recovery mode and have applied all updates from that screen. The underlying Linux seems to be fine. I can CTRL+ALT+F1 and get a terminal screen that works fine.
View 1 Replies View RelatedOn my 11.3 desktop I was annoyed by what I thought was the screen saver locking my session after an idle period, requiring my password to unlock. Well, I didn't want this behaviour and it wasn't supposed to do that, I had disabled every place in the desktop configuration that seemed to be related. I even looked into the KDE4 rc files with a text editor and they all seemed to be in order.
Eventually after some searching I found the answer: It's the setting "lock screen on resume" in the advanced settings > power daemon. Once I turned it off, it was fine; this desktop doesn't need suspend+resume anyway.
It seems that this is not a case of counterintuitive naming; it seems that in some configurations there is a bug where a stray event can trigger a screen lock by the powersaved (?). I don't really understand it, but you can start your investigation here if you are interested:
KDE4 screen lock problem
I'm running Ubuntu 9.04 (almost ready to upgrade to 10.04) with a geforce 8800 and as of a few days ago an additional monitor (of a different rez, natch). What I'm trying to do is run the second monitor in it's own X screen. It seems to function; I can run the mouse seamlessly off one screen to another and I can move files from one screen to another and back. The problem is that all I can see on the second monitor is the mouse cursor.
It appears that compiz is running cube fine, as far as watching the cursor disappear momentarily as I roll desktops. It flashes active several times while getting the desktop together on boot (this is particularly mean-spirited IMHO) then goes black. I can even see files I've dropped there when it's flashing me. It's there, I swear it, and X server is running screen 0 flawlessly. How can I turn the light on in X server screen 1?
What happens is, the program crashes for whatever reason (I don't know the exact cause, but the program terminates), and then immediately everything on my screen goes black. However, I still have a cursor, and all other programs that were running continue to run (I can access my other game servers from other computers). The cursor changes icons as I move it around the black screen, as though it is interacting with the programs that are still running. ctrl+alt+f2 still works, so at least I can restart the computer safely.
