Ubuntu :: Screen Fades To Dark?
Oct 8, 2010
and am coming from XP/Vista, loving it so far. But there is one problem I am having. After about 10-15 min of me not typing or moving the mouse, the screen dims and then goes to a screen where it asks for my password. This is getting very annoying while I am watching videos. How do I get it to stop doing this all together, I want to be able to leave my brother/friends on my computer and not have to come in every 10 min to type in my password

I have 10.04 installed in a dual boot system with windows 7 pro on 1 desktops and one laptop. Also dual boot on a desktop with windows xp and Ubuntu 10.04. The two desktops run AMD processors and the laptop uses an Intel processor. On the two desktops after booting the screen will fade to black and white and then back to color. While in the black and white the computer is frozen. This happens using Firefox mainly and other programs. It never happens using my laptop with the intel processor. Does Ubuntu 10.04 have a problem with AMD processors? It does it so much it is hard to do anything with the and desktop computers, but I have never seen it happen on my intel laptop.

I am running into a problem with my cpu using a lot of usage with no applications running other than firefox, one window... then the screen would dim as if it is going to screen saver mode, which is not set to do that after 473 minutes of being idle...because I watch full length movies... so if anybody knows about this please let me know, i dont know if I have a virus, but maybe xscreensaver is conflicting with Gnome screensaver builds or something.

Normally when I don't do anything in minutes, screen eventually fades to black. But sometimes, maybe 1/10 screen goes to gray. I can do nothing to recover from this. I can see mousepointer and it moves, but thats it. I have to manually switch power off. What is this, is this known issue? Otherwise everything works fine. I have Asus m2n68-am

10.10, and I am havingn interesting issue.During boot, right after POST and right before the bootloader screen with the progress bar and Ubuntu logo, my monitor goes completely white. However, almost instantaneously it starts to fade to black, and eventually goes away. I know it's not the white screen of death that I've heard about, because next I can log in and use my computer just fine.If anyone could point me in the right direction to try to fix this, I would greatly appreciate it. Even filenames related to Ubuntu boot would help, as I'm still learning.

I've had Windows XP installed on a Dell Inspiron 6000 laptop with 1 gig of ram and 70 gig hard disk. Today I decided to install Ubuntu 10.04 desktop edition to ext3 partitions I made on the laptop's hard disk. The Ubuntu installation went fine, and Ubuntu was up and runnning. Then for fun, I checked the available WiFi networks in this apartment building. Six were secure but one WiFi was open, so I clicked it out of curiosity. Within seconds, my laptop's 15-inch screen went super-dark, nearly jet black.I couldn't read anything on the screen. Pictures and words were still on the screen, but just way too dark to read or to see with any clarity at all. I don't have a WiFi card in the laptop.Instead I use Verizon's usb727 air card on Verizon EVDO Mobile Broadband (3G)
I don't know if the free Wifi network hosed me in some way with a nasty trick (I don't have a WiFi card in the laptop--just the usb727 dongle which is an EVDO aircard), or if it was just coincidental that the screen went super dark seconds after clicking the open Wifi network in Ubuntu's network manager applet.When I reboot, I don't see anything anymore, not the POST, not Windows XP booting up, or Ubuntu booting up. The only way I see anything now is to connect the laptop to an external monitor using the laptop's blue video connector. And even then, I still can't see the boot-up POST process, or the BIOS screen.I can only see Ubuntu or Windows XP after they've finished loading, and only on an external monitor. Did the new installation of Ubuntu hose my Dell Inspiron 6000 laptop's screen, or was it the Wifi network, or did the screen just coincidentally go bad minutes after I installed Ubuntu and seconds after I clicked the open Wifi connection?

I'm using the shiki colors theme from the repos right now. "Shiki-Noble" to be specific. When typing something into Firefox's URL bar the internet addresses have got a dark font color and are hard to read on the dark background. Here's a screenshot: FF.jpg
I've had similar issues with other themes and Firefox's URL bar before.

Just upgraded to 10.04. Screen is now unusable. It's like looking at it through a blue filter. It seems to be averaging the brightness. if there is a large dark area of screen real estate the paler sections getbrighter.The very bizarre thing is, if I switch user, whilst the theme is different, the brightness problem is gone...

Just installed 11.04 (Natty). Graphics card is Radeon 9200When I enable Cube in the compizconfig settings manager and rotate the cube, the cube goes almost black. This happens with both drag and keyboard rotate. The background is fine. Everything is defaults and no other effects are enabled.Also, the entire screen goes dark when "opacity when not rotating" is set to anything but 100%.This worked fine with with my previous version 8.04, though I think it used a proprietary driver.Questions:Should I be using a proprietary driver this card? Apparently you have to install a long list of packages first: XFree86-Mesa-libGL libstdc++ libgcc XFree86-libs fontconfig expat freetype zlib

I'm trying to install ubuntu alongside Windows 7 on a HP Pavilion DV3. When I reboot I'm given the option to either boot into windows or ubuntu (this is after running the wubi program from the ubuntu website); when I select ubuntu it says that the installation will continue but the screen then goes very dark like the brightness has been turned right down. In the center of the screen I can faintly see the word ubuntu. I've tried using the hot-keys on the laptop to turn the brightness up but this doesn't work. I've also tried installing from CD but his doesn't work either and I get the same problem. This is my first time installing ubuntu so I'm not familiar with how the installation process works. Also if any other details are needed I'll be happy to give them.

I have a desktop with AMD Sempron 3000+, 1.2GB RAM, VIA S3G Unichrome Pro IGP, VIA SATA RAID controller based disks, PS/2 mouse and keyboard running Windows XP. Wanted to move to years ago favourite (linux based systems), I downloaded Ubuntu 10.04 for i386 and am trying to install both using CD as well as USB. After the Ubuntu start-up menu for installation, I select install Ubuntu option, turn off 'quiet' so that I can see what happens. The screen goes blank dark with a flashing cursor at the top.
In the kernel messages, the see that it has detected the processor, set the clock, assigned the PS/2 keyboard to input3 and then says:
[1.911624] isapnp: no plug and play device found
After this, the system hangs. Keyboard doesn't work.

I have a Gateway NV59C09u laptop, I tried running both maverick and the latest beta of natty as live usb's to no avail. It boots fine, but at the first screen the light is so dark that I can't really read anything nor see the mouse pointer, I can just barely make out a window-looking thing. Trying to increase the brightness using my F-keys doesn't do anything.
It's gotta be some kind of graphics related issue, because booting the alternate iso works fine. If I could figure out a way to boot the ubuntu-desktop live image via a different video driver that would probably work, but I'm not sure how to do that (ctrl+alt+f1 does nothing).

I'm kind of new to linux, but even I shouldn't have this much trouble, because I've been reading faqs like crazy and tutorials, but I just don't understand what's going on. I'm installing Linux Mint on my old machine now and it's installing good, but I try to install Fedora 10 and I've been having problems. It works fine in VMware, but when I try to load it from a live CD to install into the drive, on the initizialize process it say's "failed ata something something", then it goes to a bar and then it goes to a black screen and it hangs there. I did 5 md5check sums on the same iso, I'm not sure what's going on?

Despite being warned from a friend of mine who works for Intel that the new version of Ubuntu 11.04 sucked? I upgraded from 10.10 which worked perfectly fine and did everything that I wanted it to except work with my COBY MP3 player which is what I hoped 11.04 would do. It all worked great until I rebooted. I previously had the main screen on the left where all of the menus are and the right screen was the 2nd monitor.
Once it rebooted it let me login and loaded the desktop but the main screen is now on the right with that stupid application bar going up the side, all of my folders, etc. are all there but NOTHING is clickable, even the icons up in the right corner where you logout, etc. will not do anything other than highlight that you have clicked on them, the hard drive light flickers for a few moments then nothing.
Also the left hand screen is completely blank unless I move the mouse cursor through it. If I just leave the computer sitting there eventually the screens go dark and the monitor lights start flashing like it is supposed to but if I wiggle the mouse the screens come back on and the mouse is there but there is no login prompt to let me log back in. Pardon my French but this OS is a piece of <bleep> and sucks just like I was told.

I recently installed Kubuntu 10.04 on a Toshiba Satellite 5205 laptop (which is prone to overheating, if it helps - it was on a platform in the back for airflow, though), which worked great for about 4 days.
Recently, I picked it up (looking for a USB port) and rotated it around a little bit. However, after this, the screen was darkened (not fully), and I could move the mouse for about half a second, after which it jumps back to the upper left corner of the screen. Rebooting doesn't help.

I've installed Fedora 13 x86_64 and am not able to hibernate (though suspend works fine). This is the case either with or without the proprietary Nvidia drivers from rpmfusion. When I click System -> Shut Down -> Hibernate, the screen just goes dark. Moving the mouse activates the display and the password confirmation box appears. Judging by the disk activity light, nothing is written to disk. Swap space is configured correctly.
Looking at the last few lines of /var/log/pm-suspend.log I see this:
It looks like grub (or the absence of grub.conf) is interfering. Problem is, I'm not even using Fedora's grub to boot the system. I'm dual booting with Ubuntu 8.04 and am using that grub. The section from that grub's menu.lst is:
But of course Ubuntu 8.04 is pre grub2 so how do I satisfy Fedora's grub.config without messing this up?

I am unable to boot my laptop in the usual way. The fedora emblem in the centre of the screen appears and starts to turn from white to dark blue in the usual way. When it is almost complete it stops.
In order to make the machine boot i hit escape and a message says leaving interactive startup mode. At this point the machine continues to start up.
When i do manage to get it to boot i get the following message repeated many times:
I should also add... The laptop will not close down, once i click switch off the screen turns blue and displays the fedora emblem in the centre. At the top right text says "Shutting Down" but at this point the system hangs.

I was changing some settings in ATI Catalyst Control Center on my laptop; when I had my cursor on the contrast slider, the mouse slipped and slided the marker to the far left, removing all contrast; now, everything is dark grey (once I'm at the login screen, the very first bootup screens work) and I am unable to use my laptop.

I'm having a problem with Firefox going dark (application so busy it stops responding) while it is loading web sites. When I switch to the terminal and do "top", it shows "compiz" and "Xorg" as the most busy applications. I'm using Ubuntu 10.10 and Firefox 3.6.17. Anyone have an idea of what might be causing this?
