Ubuntu :: Run Program When Screen Locks

Feb 7, 2011

I would like to run a command when the screen locks, and another when it unlocks. I work in a shared office space. When I leave my desk (and the screen locks) I would like the webcam motion capture software 'motion' to run, in order to record anyone who uses my computer when I'm gone. Likewise when I come back and unlock the screen I would like it to pause.

Ubuntu :: Emachine Nvidia Crash - Screen Locks Up Or Will Distort In Multicolor Stripes Across Screen

Oct 2, 2010

I have an Emachine that my uncle gave me and I thought that Ubuntu would find a nice home in the cozy case and well.....

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?

Ubuntu :: Computer Locks Up And Then Goes Into Login Screen?

Aug 6, 2010

Recently, 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

Ubuntu :: Screen Freezes / Locks Up Periodically?

Nov 23, 2010

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 )

Ubuntu :: Dragging Window Locks Screen And Computer

Mar 2, 2011

I 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.

Ubuntu Installation :: Install Crash - Either Locks Up Or The Screen Goes Black

Feb 8, 2010

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

Ubuntu Networking :: Wireless Connection Drops When Screen Locks?

Jan 22, 2011

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.

Ubuntu :: Kubuntu 10.4: Locks And White Lines Spread Over Screen?

Jun 29, 2010

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?)

Fedora Installation :: 12 - Splash Screen Locks Up ?

Jan 9, 2010

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.

[url]

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....

Debian Multimedia :: Disabled XScreensaver Still Locks Screen

Fedora :: Screen Locks Up During Graphical Boot After Update?

Jan 5, 2010

After 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-*.

Fedora :: Gnome: Screen Dims And Locks Up Processes?

Jun 8, 2010

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.

Ubuntu Networking :: Laptop Locks Hard On Login Screen If No Ethernet Cable Plugged In

Jul 15, 2011

Acer 5250-BZ475 laptop, fresh install of Ubuntu 11.04. Boots up beautifully as long as an ethernet cable is plugged in. 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.

Ubuntu :: X11 Screen Locks Up In Endless "Starting File Manager" Loop

Jun 7, 2011

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.

OpenSUSE Install :: 11.3: "screen Saver" Locks Session Even Though Disabled?

Aug 19, 2010

On 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:

Ubuntu :: Make An All In One Program Screen

Aug 3, 2010

Im trying to make an all in one program splash screen for ubuntu.

the idea behind this is, I have alot of staff at my store who will be using a system system for a few programs, but almost none of them have any real use of ubuntu.

What I would like to do is have them log in and instead of seeing the desktop have a splash screen pop up with the program choices they can use, all in one place.

Ubuntu :: Launch A Program Onto Another X Screen?

May 11, 2011

This is for a live performance type of setup. I have 2 graphics cards. One is attached to 2 projectors, which are what the audience sees. The other has a single monitor, which is backstage. The 'front' graphics card is configured in Twinview, and the 'backstage' one is configured as a second X screen by the nvidia settings control panel.

What I'd like to do is launch my show program from a terminal on my backstage screen, but have it show up on the other X screen, the 'front' one. X is amazing so I'm sure it can be done, but I'm having a hard time figuring out exactly how.

Personal Best for self-solving my own thread question:

Code:
DISPLAY=:0.0; xclock
launches on display 0
Code:
DISPLAY=:0.1; xclock
launches on display 1

Ubuntu :: Installed Program Opening With Blank Screen

Sep 9, 2010

I am using ubuntu 10.04 and after installing some programs using the package manager I try to open the program and all I get is the title bar and a blank white screen. I searched the forums and found a thread from awhile back saying to create a new user and see if it persists. I tried that and it does the same thing in the new user. One in particular is gnucash. The program sometimes works but the tutorial does the white screen. I also reinstalled the package several times with no luck. Other packages do the same thing like thunderbird.

Ubuntu :: Flashing Splash Screen Of Newly Installed Program

Nov 25, 2010

I have recently installed a program called IDA-STEP (manually off the web) on my Ubuntu 10.0.4 system. I unzipped the program folder to /usr/local/ida-step, and ran the executable to install (sudo ./ida-step) it. Now, every time I want to run the program I have to type "sudo ./ida-step" from within the folder to begin the program. However I also recently modified a copy of an existing *.desktop config file so that I can launch ida-step from the applications menu (and its in /usr/share/applications).

When I use this latter method to launch ida-step all I get is the programs initial splash screen flashing on and off (everything else in the background remains unaffected) - but the program never launches. I can replicate this behaviour if I launch the program in the terminal by typing "./ida-step" (rather than "sudo ./ida-step" which works fine).

Debian Configuration :: Startup Program Screen Too Small?

Oct 10, 2015

The "System Settings/Startup Programs" window is large enough but the "Program" column is too narrow and it cannot be resized. The window can be dragged to make it larger but not the individual columns. It looks like a Java listbox with "Enabled = false" set. This occurs in Debian8 64 bit and also in Mint 17 and Mint LMDE2. I am surprised nobody else has raised the issue. I have a basic setup with 22" screen and 1680 x 1050 resolution. It occurs with Nouveau and NVidia drivers. It is not a critical bug so I have coped with it for 2 years but it would be nice to see it fixed. Unfortunately I could not upload a screen shot as "board attachment quota has been reached".
