Ubuntu :: Enable A Black Screen Screensaver While The Machine Is Sitting At The Login Screen
Oct 1, 2010
Alright guys. I need to find a way to enable a black screen screensaver (or turn off the monitor, or something to avoid burn in) while the machine is sitting at the login screen and completely turn off the ability for the computer to sleep. how I can accomplish that?
Does anyone know a way to activate a screensaver at the login screen? I've got about 5 machines here, and I'd really like the ability to just have the screensaver come on after 5 minutes of sitting there with nobody logged in...
Even a way to blank the screen would be nice. However, if we were to blank the screen, I need to ensure that it doesn't do a DPMS blanking, since we use calibrated monitors here, and turning them off sucks.
I was messing around with the screen orientation and thought it would be funny to orient it sideways. Big mistake The screen went black.I can force a shutdown, login and I get the same black screen. I tried hooking up an external monitor and the monitor showed no input so I'm guessing my laptop doesn't have that capability with Fedora.This is my main computer.
My last setup (years ago) ran fluxbox so because it was familiar I installed it as a secondary to xfce right off the bat. I download a lot of different stuff because I like to try out all the apps I can find but somewhere I broke something. I can still run fluxbox fine, but nither the Xubuntu nor Xfce sessions will run now. Last thing I remember changing was pulse audio(removed it for an experiment I was trying with jack audio), not sure if it is connected but when I try to login to xfce the screen goes black, flickers a few times then it brings me back to the login screen.
I tried failsafe but everytime I do my monitor gives me a "frequency out of range" error. I tried purging and reinstalling xubuntu desktop and xfce settings but I am thinking its my xorg config. My laptop is a Toshiba satellite M305D-s4830 with ATI Radeon 3100 mobile graphics card and I am running Xubuntu 10.10. Unfortunately I also broke the screen, so right now I am stuck with an external monitor till I get a new one.
This problem started within the last few minutes. I run a program in my browser that uploads data from my machine (ubuntu) to another machine (Fedora 13), for manipulation and then spits back the data that does not match our standardised information.
When I tried to run it a few minutes ago, it seemed to take a long time to make the connection. I went back and checked the machine, everything was connected and fine. I decided to reboot the machine from within KDE and then try again. Same result. I went to the machine again and tried to login through KDE, the screen goes black for a few seconds and then returns me to the login screen. I switched over to a virtual terminal and was able to login using the same credentials. I checked the .xsessions-errors file and this is what I am seeing:
I have a few machines set up and running Red Hat 4.1.2-42 in a computer lab. I also have a single test machine running the same version. The machines in the lab work flawlessly.However, when machines are on the login screen, they don't go into power saving mode. That is, after a certain amount of inactivity, the idle login screen should be replaced by a black power saving screen. But this does not happen. The monitor should go into standby (the little green light becomes orange, and the whole screen shuts down until you move your mouse again...you know the drill).I know this is supposed to be the case because this works on the test machine. It just doesn't work in the lab. I think it has something to do with gdm, but I can't for the life of me figure it out.
all I wanted to get was the "rss-glx"-package as additional screensavers. I am not proud of the results:So I used the Synaptic tool, and since that time the gnome-screensaver shows a black screen instead of any GL-animation in the preview-windows (the small and the big one). The simple screensavers still work (e.g. the Gnome feets).I propably made it worse when trying to uninstall gnome-screensaver and installing xscreensaverxscreensaver crashed on each preview (if the screensaver was installed) and printed an "exited abnormally" (yellow lines on a black screen).Then I was trying to get the original state back - without any "rss-glx".Still not succeeding, the GL-screensavers show nothing except a black screen (e.g. AntSpotLight).So what do I have to do to get back the original state (or to run rss-glx)
I've got Ubuntu 9.10 with a user account for my wife, and one for myself. "Wake-from-screensaver" should result in "choose user" without having to enter any password. I know how to do that in Windows, but I'm not good with Linux (yet). get past the login screen without passwords (after booting, and after choosing "switch user"), but once the screensaver kicks in and I wake it up again, the system does not present the "choose user" screen. Instead, it either turns off the screensaver and presents the desktop of the most recent user, or (if the screensaver is set to lock the screen) prompt for the user's password (which can be handily surpassed by clicking the "switch user" button and choosing the same user again). So, the login ("choose user") screen has been dealt with. How do I make the (any) screensaver return to the login screen at wake, rather than to the current user's desktop? Windows can do this, I'm sure Linux can too - but how?
I can't seem to get Ubuntu to run on my old Dell Dimension 2300. It boots to a purple screen then it goes to a black screen with a load of writing nothing else happens after this screen. [URL] Could someone advise how I can get it to work?
I just bought this desktop from my friend and it runs win 7 and ubuntu 10.04. it worked very well the first two days until I changed the hostname of the system.
I did like: hostname myNewName
And everything worked fine. The problem now is when I start ubuntu and and reach username and password screen , I enter my password to login the screen becomes black and return me again to the screen where I put my password again. If I entered wrong password , the system message stating wrong password. On the other hand, when I try to run ubuntu from live-cd I can login easily and access my account.
My friend told me he removed Naultius package and reinstall it for some reason before he gave it to me. Note windows 7 is working properly.
My OpenSUSE 11.2 is working fine as samba server, no problems, but I have a problem with KDM.My default init runlevel is set to 5 and every time I try to login at KDM (KDE4), the monitor goes black and returns to the login screen.If I hit Ctrl+Alt+F1 to go to console and start /usr/sbin/console-kit-daemon manually, press Ctrl+Alt+F7 to return to KDM login, everything is fine.What do I have to do to fix this issue?
So my problem is I recently upgraded my Graphics driver and shut down to log in to windows (yes i dual boot) About 10-15 min later i went to log ubuntu the splash/loading screen what ever you call it worked normally but on reaching the point where one would login I was presented with a Blank screen. Ctrl-alt-f1 also presents me with a blank screen.
I've been using Ubuntu 10.10 for a while it is so great But for the first time, I've booted my laptop on battery power instead of AC power. I have a black screen on the gnome login and i can hear the ubuntu sound. If i press CTRL+ALT+F2 the screen switch from black to the login (terminal version). The problem only appear when i boot from battery power...if i boot from AC power everything is fine !!! I can see the gnome login page. in fact i've reinstalled ubuntu same problem. I think it's a bug with the release. My laptop is a HP TX2000.
Ubuntu 9.10, x64. Around 30-40%of the time, after i login, I just get a totally black screen. If i leave it for a few minutes, nothing seems to happen. Whether or not i get login seems fairly random, and I don't notice if there is any common factor- This is always from a clean boot, and i could be on power, or not on power.This is on a HP 6730b, so the video should be a Intel GMA 4500.
I tried to install Ubuntu 9.10 on one of them by default installation. For the moment there is only one user declared. The installation seems OK, except that Ubuntu didn't find my PPPoE connexion. When I logged in, I got a blank screen with the mouse cursor (it moved, but when I left or right-clicked nothing happened) and on the left something looking like two 1-pixel wide menus, as if the system had understood there were a dual screen. These menus could roll and unroll, and I think I even once managed to shutdown by going to the last invisible item thanks to the keyboard arrows (I'm not sure, because I had also clicked on ctrl+alt+suppr, so it could be a delayed effect of that).
I restarted the computer several times, to get no more than that. When I'm in Gnome safe, everything is OK but I don't have any root privilege there (I guess it's normal): for instance, I can't set up the internet connexion. My 20" 4/3 Philips screen is recognized. Then I changed the screen frequency: it's still OK for Gnome safe session, but now, in the Gnome normal session, instead of a black screen with 1-pixel wide menu, I get a black background picture with white light coming from above and reflecting to an otherwise invisible floor. The mouse cursor is moving, but this is the only thing which works.
I just Installed Ubuntu on my PC (win XP-pro) using wubi, by downloading the .iso from webpage and burned it to cd. The installation went fine, but when I login the screen goes black. I can still see my mouse pointer and one vertical pixel line of the desktop. Could it be the graphics drivers, if so how can I update/change them, via rebooting in safe mode and using command line?
I get a black screen (with tiny bits of white on opposite corners of the screen) every time after logging into Kubuntu Lucid AMD64. The only thing I can do is move my mouse pointer over that black screen which doesn't go away. I booted into recovery mode and with command prompt typed "startx" to start graphical mode. That resulted in the same black screen. Then I decided to reboot and install Fluxbox via the command prompt under recovery mode. Now, I'm able to view graphically under Fluxbox after selecting it over the default KDE and logging in. But how do I get regular KDE/Kubuntu to work again? I don't know what happened to make it stop working!
I just used a LiveCD to install Ubuntu 11.04 x64 on my HP desktop. I'm not sure what you need to troubleshoot. It has the following specs:
HP Pavilion Media Center m8539f PC AMD Phenom X4 9550 QC Processor 5gb ram, 750 gb hdd Came with vista home prem, nothing left of that except the old restore partition, which I have left intact. It had Windows XP installed recently, but that's completely erased. GeForce 9300GE Video Card
Anyway, I want the x64 so that I can have access to my RAM, among other things.
After installation with the LiveCD, it will come on, present me with generic/safe/etc boot options, and then when either safe or generic is chosen, it goes to an (active?) cursor for a few seconds before revving the HD, screen going black, and then... nothing. No indication it is even still powered at all except the light on front.
Iam facing a weird problem with ubuntu since last week... Starting system-->selecting ubuntu from grub menu-->ubuntu splash screen comes and it loads fully-->black screen is displayed instead of login window.. Restarting the system and the prob is gone..able to login properly..
This problem is ocurring randomly..sometimes i can login in 1st attempt properly,other times i have to restart the system twice or even thrice to get to the login screen.. what can be the possible reason to this...I have not done any updates also..
After applying an update about two or three days ago, I restarted my system and now I'm getting a black screen at login. I can hear the brief drum sound clip that plays when the login dialog box pops up, but the screen is completely black and I can't see anything. I'm still able to access low graphics mode via the fail-safe option in the recovery mode menu. So far I've tried the following commands in the terminal:
1st Problem:The problem that I am having is for Ubuntu 10.10. When logging in for some reason it will:1. Login and play the Ubuntu login sound.2. Will start loading the desktop and panels.Right after #2 it goes black and kicks back to the login screen. I am not sure what to do since it constantly does this. It renders the computer useless if I cannot get passed the login page. Yes the username and password are correct.2nd Problem:Before this 1st problem occurred this has also been a problem that has not went away.When I used to be able to login to the desktop I have just the panel on the top of the screen with the traditional Ubuntu "start menu", "system", etc. For some reason the right side which is the other half of the panel will not load. The only solution which fixes it while I am on the current session is to right click the panel and click Minimize/Expand button which toggles to center the panel on the top of the screen. Now when I click Expand its like the problem never happend, but this only fixes it for that session.
I have ubuntu 10.04 installed inside the Window xp.I dont know what went wrong.Today,when i started ubuntu it gives the black screen for login,if i fil correct username and password still black screen is there.I need Gnome-GUI back as it was before
Got my Slack running on vostro 1310 for a while now. But just Today... first for what ever reason my wifi stopped to work (at boot time) even though interface was up as usual, driver was loaded, supplicant has not been touched etc. So I wired up a LAN cable and the at boot time I saw an information from eth0 that packet length is 0 and cannot be parsed (great no network at all). Tried to investigate the problem on a different machine, and one of the suggestions I've found was to set router to no security and see if wireless will connect. I thought that it would be a good idea to reboot the machine to attach to the rooter at boot time and no eth0,wlan1 tries to connect to the network and then I get a black screen instead of login window
so i have been trying to install ubuntu for quite some time now and i have run into a bit of a roadblock.
I have tried to install 9.10 and it installs just fine (the GUI works just fine and everything seemingly goes ok), however when i go to boot it, i get to a flickering screen asking for my username and password (this is not the gnome login screen, it is just a blank black prompt asking for me to login). however, the flickering is inhibiting me from easily entering anything in from my keyboard. Thus, i cannot log in to fix the problem (i cannot enter my password because i dont know if the keys i am entering are being accepted or not). and recovery mode does the same thing.
This happens if i try installing it straight up, or if i install it inside windows. I have tried all kinds of boot options and install options (all that acpi crap) but none of it works.
i even tried installing some of my old copies of ubuntu (8.04), but when i do that the grub cannot load the linux kernel. I have also tried both the 64-bit and the 32-bit versions to no avail.
I am running an ASUS motherboard, AMD quad core x64, dual Nvidia geforce 8600's, 6 gigs of ram, and PLENTY of hard disk space.
I am not a noob to linux at all, but i have never encountered a problem like this and i have no clue how to fix it. Hell, i dont even know how to go about fixing it without logging in.
I just installed Ubuntu 10.10, and I really have no idea how to login. When I first start it up, it is a black screen and a lot of codes and stuff pop up. It says to login, so I do, but I don't know how to get past that. How do I get to the desktop? I have no one else to turn to...
