Ubuntu :: GNOME Loses Color Depth After Screen Turns Off

Mar 13, 2011

Problem appears every time I leave my computer for a while and my screen turns off because of inactivity. Then after screen starts again, my desktop looks like it lost color depth. I can see wallpaper that consists of big blocks of color tones instead of being smooth. Temporary I had to disable blank screen during inactivity in Power management settings. I have installed:

Ubuntu 10.10 x86_64
kernel 2.6.35-27-generic
GNOME 2.32.0

My graphics card:

ATI Radeon HD 5470 512MB
ATI/AMD FGLRX driver installed

Debian :: Set Color Depth To 32 In Gnome?

Jun 22, 2010

Just installed 32 bit Lenny 5 in virtual box, a software computer, and virtualbox say that it wants the color depth changed from 24 to 32. Tried manually changing xorg.conf but then X would not start saying: 32 depth was inconsistent with 000 weight.

Ubuntu :: How To Increase The Color Depth

Apr 6, 2010

I've a laptop from 2001 with 512MB of RAM, and I was running Windows XP, and the laptop wasn't coping very well with the huge demands of the applications of today. It was only yesterday I installed Ubuntu alongside XP and I was surprised to see how fast everything was!

The only thing that's bugging me a bit is the screen. Some parts of the desktop shows some banding where there is meant to be a gradient, probably telling me to increase the color depth. Is there a way in Karmic Koala to change the color depth? I tried using sudo gedit /etc/X11/xorg.conf but when the editor shows up with the setting file, it's empty.

Ubuntu :: 9.10 Keeps Switching To Low Color Depth?

Apr 12, 2010

Basically I've just installed Ubuntu 9.10 on an old Acer Aspire 3000 laptop. When I first did the install I observed that the screen color depth was very low so after browsing the forums I ran the latest updates and then everything was perfect.

However after a restart the color depth reverted back to low. I created an xorg.conf file and set the default depth to 24. However no luck. I then set the color depth to 16 in this file and restarted. This time it switched to the 16 bit color depth, however after a restart again it all reverted back! I tried changing the value again but it is now stuck at the low color depth again.

The driver I am using is the updated SIS driver that was provided from Ubuntu for the onboard 661 SIS video card.

Ubuntu :: Karmic - How To Change The Color Depth

Mar 11, 2010

I am running Karmic Koala on a Dell Precision M90, and have some problems with my color depth, or at least that's what I believe. I have googled this problem numerous times, reading a lot about /etc/X11/xorg.conf, and have created numerous files in that location, with all manners of (probably) valid contents. I have yet to try invalid contents, in the hope that Linux is reading the file, and doing so would crash the system. This is my current xorg.conf, after many iterations:


Section "ServerLayout"
Identifier "X.org Configured"
Screen 0 "Screen0" 0 0
InputDevice "Mouse0" "CorePointer"


Now, is there some other place to change this? Should I sacrifice more virgins to Cthulhu, or is Hastur the one to ask in these situations?

Ubuntu :: Changing The Color Depth From Whatever It Is Now To 24bit?

Dec 29, 2010

I am trying to create a media server, and I decided to try out Ubuntu, but I'm having trouble figuring this out. I have taken a suggestion that I got from another forum, but it did not work.

I'm using version 10.4 and I have to get it to at least 24 bit so I can run XBMC. I have a friend that works for red hat and he said I needed to find the restricted driver or something, but I can't find it, and he doesn't know where it might be on Ubuntu. So, does anyone know how I can change my color depth to 24bit?

Ubuntu Networking :: 10.10 Reverse X11vnc Color Depth Changes?

Nov 15, 2010

I have looked around and haven't had a lot of luck finding any information on this. I could be blind...but I'm not sure, haha.

I do a lot of remote support for my clients (I do PC repairs and training). I have recently starting suggesting to some of my basic users that they give Ubuntu a try. So far it has been very well received and they are loving it. The problem I am running into is that some of them use laptops in multiple places, and some use routers that are not easily configured. In each case it makes port forwarding a large pain in the behind to allow for remote access.

I have started using the X11vnc reverse connection and it has been working well, except for the fact that it is using high quality color depth (24bit I think?). I know when starting the connection from my end I can set the color depth, but is there any way to set the depth of a reverse connection?

Also, I understand that using just vnc over the Internet is not secure. I need to look into a decent guide to set up SSH tunneling for this. I don't suppose anyone knows of a good guide for 10.04 and 10.10?

1. Identify what my current color depth setting are? (default opensuse 11.4 KDE install)

2. How do I change it? Am assuming it is set to 32bit now, would like to set it to 24.

The reason is my little netbook really burns up when i play a video.. acer aspire one and one of the reason why I installed linux over windows 7 was that I wanted my laptop to run faster ... apart from the fact that I would have installed suse anyways!!

Ubuntu :: Monitor Display Awful (color Depth) Acer Aspire 1710?

Oct 29, 2010

I've been desperate to successfully install Ubuntu on my Acer Aspire 1714SMi (old and huge, I know), but the display suffers from a greatly reduced color range, strange white haze/ fine vertical lines and virtually ilegible text. I took a screen shot as I know it's hard to describe these things, but it looks normal on the image! The Graphics Driver is nVIDIA GeForce FX Go5700 128MB. The display is perfect on XP.

I downloaded some NVidia Drivers for Linux from nVidia & from here: [URL] Can't get any of them to work, and I find it hard to believe it's so difficult to get a basic display to work. I'm about to give up.

Software :: Screen App / Retain BG / Color Background Color Gets Lost

Jul 6, 2009

I am using the screen app, and have set bce to on, and issued the following commands to set my background and foreground color: tput setab 4; clear; tput setaf 7; clear;

This temporarily sets everything properly on my screen. However, when I issue any commands that change or set their own background color (for example, when I issue an "ls" command with colorized output), the background color gets lost for any new output and I have to reissue the commands listed above in order to retrieve my background color.Ideally I'd like to keep my background color when issuing these commands, as it serves as a good way to remind me of what environment I am currently issuing commands in.

Debian :: Screen Session Loses Write Privileges After Logging Out?

Sep 11, 2010

When I start a screen session over SSH, I can edit and save files from within the screen session before I log out of the SSH session. But after I log out and log back in, I find that the screen session has lost write privileges, so that I can no longer edit or create any files, even within my home directory. How do I prevent this from happening?

Debian :: Screen Turns Off During Installation

Jan 22, 2016

I believe it might have to do with dpms (according to KiPi on the #debian-boot chatroom) but I'm not entirely sure why my monitors keep turning off 10 minutes into the installation. I have tried using Live CD and a netinst version of the Debian 8.2 installation methods.

I'm going to try to disable dpms in the Live CD and hopefully that works.

Ubuntu Multimedia :: Screen Turns Black & White After Going Into And Out Of Fullscreen

May 30, 2010

I insert my DVD into my machine. The little "waddya wanna do" window then opens, and I select "play in VLC." I then press the play option on the video menu (not the play button on the VLC controls). Then the VLC window turns black, or the part where the video is supposed to appear does, anyway. So double-clicking to get to fullscreen sometimes fixes the problem, but then I can only view it in fullscreen, not good. It didn't fix the problem this time, so I double-clicked again to get out of fullscreen. Then my whole display turns black and white. WTH? The display problem fixes on a reboot.

This happens on a regular basis when I try to play movies. My display is, right now, black and white. After I finish this post I'll restart my computer to fix the colors.Also, it should be helpful that when I move the VLC window or am going to/from fullscreen, I can see the movie for a split second, and in full color. The rest of the screen stays B & W, though.Also, for some reason, when I play a movie, VLC open two windows: one with the video, and the other with a visualization and a title bar saying "VLC (X11 output)"

Ubuntu :: Compiz-Fusion - Turns To A Blank Screen Of White With A Mouse On It

Jan 6, 2010

Just installed Ubuntu 9.10 64 bit on my computer dual booting with 9.10 32bit. Was hoping to move to 64 bit to get full use out of my RAM and CPU. The issue is that when I tried to run Compiz-Fusion that I got from the Ubuntu software repos that came with 9.10 nothing would change. I tried to make a 4 desktop layout with a cube like I have on the 32 bit OS and nothing happens. So I right click on the Compiz icon and select the "reload windows manager" tap in the drop down menu and every time it turns to a blank screen of white with a mouse on it. I can move the mouse and I can even use some of the new settings I changed but I cant see anything else besides a mouse and the white screen. I feel as thou I am using a version of Compiz that is not compatible with 9.10 64 bit.

Ubuntu Installation :: Get To The Login Screen, But When Hit Enter Eveything Turns Black?

Nov 30, 2010

I'm trying to install the latest version of Ubuntu Studio. I tried it a few months ago with my HP... a live system worked fine, but when I installed it, it would go blank after the splash screen. I assumed it was some sort of incompatible graphics driver and gave up since I don't know enough about Ubuntu yet.Now I have a spare Dell XPS desktop sitting around and I got the latest version of Ubuntu Studio and tried it again. The install goes by erfectly, this time the welcome screen actually comes up and I can see my username. As soon as I hit enter, which I imagine should bring up the password prompt, the entire screen goes black and won't respond to anything.

OpenSUSE Install :: 11.3 - Screen Turns Off After Auto Reboot

Feb 6, 2011

I have a fresh install of openSuse 11.3 installed. But after the install the auto reboot nothing happens screen turns off, I restart comp grub came up.
OpenSuse (Default)
Failsafe openSuse
Windows 7

I select default the little gecko loading screen comes up then after 15sec screen goes black screen actually goes into idle mode, button pressing mouse moving nothing effects it. I reboot again select failsafe, text screen comes up going through list everything green, then screen turns black doesn't go into standby just black screen. I reboot try default with nomodeset loading runs same as failsafe except when comes to x-server screen goes black.

I have 2 displays a 18" Dell digital lcd Monitor, and my 26" TFT TV, They are both connected to a Gigabyte Nvidia GeForce 8400 GS, TV with HDMI and Monitor with DVI-I. I have a second 18" Dell LCD Monitor, which I had connected with D-Sub but I couldn't get all 3 working so disconnected second monitor, as i wanted tv over monitor. I had ubuntu 10.10 running before the opensuse 11.3 install it worked fine but i wanted to try suse.

I thought it might have been that I was picking KDE desktop then adding Gnome later in installation, so tried reinstalling default install same problem, tried gnome alone same issue, tried gnome and KDE and same issue. so i put original idea back on KDE and gnome later in install. and im sticking with this until I fix as its the one I want. But if I really have to I will switch back to ubuntu. I have no Linux experience.
