Ubuntu :: Changing GPU Clock Speeds Results In Black Screen?
Sep 13, 2010
I've recently done a clean install from Karmic to Lucid, everything went well first time, although I noticed that my GPU performance seemed to drop. It wasn't amazing to begin with being an older AGP card (nvidia 6800GT), but it was enough of a drop to make me look for a solution.
I thought maybe the drivers in Lucid were to blame so I recently added the ubuntu-x-swat PPA
[URL]
to get the most up to date drivers.
Performance didn't go up, so I tried the 173 version of the drivers to see if that would help, but I had no luck.
Today I'm pretty sure I downloaded an update from the above PPA and since then every time I change the clock speeds (via the Coolbits option within nvidia-settings) on my card I get a black screen, there is no response from any input device and I have to hold the power button to turn off the PC.
I want to know if there is anyway to check recent packages I've downloaded, and also if anyone could shed some light as to why changing the clock speeds of the card would result in a black screen and no response from the keyboard or mouse.
I'd also like to point out, that I've been changing the clock speeds of the card since I first installed Karmic with no problem. Additionally before I downloaded today's updates, even with the new packages from the above PPA changing the clock speeds worked perfectly. It seems that something I downloaded is to blame.

I own an HP Envy 14 [url]. Letting Ubuntu (or any Linux) attempt to boot into a Live CD without changing any parameters results in a black screen, but with everything else working (for Ubuntu, that means the login sound is played). I've discovered that putting nomodeset in the kernel line will allow me to get so far as a command line, but I can't startx from here (I get "Screen(s) found, but none have a usable configuration."). I think my issues have something to do with the dual/switchable graphics in my laptop.

I have a fairly old laptop that has been running 8.04. I got the 10.04 alternative CD and updated the system. After the reboot the screen just stays blank. I have left it running for some time to see if anything happens. I have tried to CTRL+ALT+F1 to get a console. But nothing.
So I looked up some solutions on the internet and decided to try xubuntu too see if this may be related to the low (old) specs of the laptop. Got the xubuntu CD. But even booting from the xubuntu CD (try before you install) results in a blank screen. 9.10 boots fine from the CD, but I have not tried to install it yet.

My EVGA 7600GT video card suddenly died. A friend gave me an EVGA GeForce 8400GS to replace. I'm running a homemade AMD Athlon 64 3700 box with 2 GB memory and 2- 250 GB WD hard drives. First drive has Win XP OS and second drive runs Ubuntu 10.04. I was using Ubuntu about 99% of the time before the video failed. After installing new vid card, I deleted old driver in Win and installed new driver off the CD that came with the card. Windows system was then 100% back to normal.
My grub booter is set up to default boot to Ubuntu with Windows the last choice which can be done manually. After installing new Win video driver and confirming it worked, I re-booted the computer and let it go to Ubuntu. The results was the usually flashing cursor for about 10 seconds, but instead of the Ubuntu splash screen popping up, the monitor went black for about a minute and then shut off the same as if I had shut down the computer.
That was over a week ago, Since then I have tried everything I can think of but nothing changes. I have read and tried numerous ideas from other posts on these forums (such as hitting ctrl, alt, +/- to change screen resolution) but I still have a black screen.
I tried booting up from my original install CD which is ver 9.10, not 10.04 (I upgraded to 10.04 by directly downloading online and never made a 10.04 CD). I can get into an Ubuntu desktop with that old CD and I checked to see that it showed the highest resolution for my monitor (a 22" wide flatscreen whose native resolution is high-1920x1280?? don't exactly remember at the moment). I also tried loading the generic Nvidia 185 driver but it didn't seem to take. I downloaded the latest Nvidia driver for Linux onto a thumb drive and tried to install it here, but was refused because the message said it had to go into "root" and I didn't have permission. I don't know how to establish permission when booting from an old install CD. I'm sure I have administration rights under my regular 10.04 installation but can't see it due to the blank screen.
I've tried at boot to go to the recovery mode listed right below the default Ubuntu boot option, but when I do, a whole series of text flashes on the screen and rolls down to the word "done" with a flashing cursor at the very end, The cursor flashes for about 5 seconds and then the screen goes black. I've tried to enter some quick text at the cursor to keep it from going black, but it doesn't stop it. It wants to go black and it does so.

NVidia FX5200: nvidia-glx-173xxx The problem is that, when I install it, upon rebooting, I get a black screen with one blinking underscore at the top left corner. I somehow managed to get into the console and .. there's something wrong with the video card driver ( no way I could catch it into a picture ).
This was the exact reason why my Fedora CD was laying on the corner for months - I remember having this issue earlier as well.
Is there a way to fix it or at least, recover from a broken video card driver ?

In ubuntu 10.04 I have compiz installed and when I try to rotate the cube or simply change desktops screen goes black but not entirely, I mean I can still see the cube. This happens only during the change of desktops. Its very annoying,it doesn't create trouble but I cant see the cube effect.

In the clock display (Kubuntu 10.10 32-bit defaults at the lower right in the task bar) I have been having a problem. When I right click on the clock (is there a name for right-clicking when referring to both right and left handed people?) or sometimes when I just run my mouse over the clock, it changes from CDT to UTC. Doing it again reverses that. I'm speaking about the actual clock on the task bar, not the pop-up panel (tool tip?) that comes up when you roll your mouse over it.
I have both time zones selected so that I can see them in the pop-up info panel when I run the mouse over the clock for a second. But, normally, I just want the CST/CDT displayed always, in the task bar.
I've looked at all the options I could find and haven't found what I missed. It started up recently, so it was probably some setting I changed, but now can't find.
A minor problem, but annoying. Anyone? If the answer is already out there, link me up!

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.

The clock keeps changing back to UTC which is not so good. My local timezone is about UTC +7. It appears to be good until I reboot. I can change manually in the bios or enter the following command hwclock --systohc --localtime No matter what it goes back to UTC. I checked the timezone data is correctly recorded and it is...
The command hwclock returns Wed 23 Feb 2011 08:18:05 PM ICT The command date returns Wed Feb 23 20:19:25 ICT 2011 so this shows the system time and the hardware time are the same but they use the 12 and 24 hour clock which is strange since the bios supports only the 24 hour clock. I wonder if the time / date syntax has to be presented in the same way on both the system and the hardware? The time ICT zone appears to be correct.

(bare with me as I am sort of new with scripting) I am trying to figure out how to run a script that does a basic chkconfig and to get only those services that are running, but changing the color of "on" to red in my output file. Here is what I am working with so far:
Quote:
#/bin/bash
RED=$(tput setaf 1)
BLK=$(tput setaf 0)
[code]....
*I had to substitute a "-" and <colon_symbol> for ":" in front of the on's, because the forum thought they were smiley faces (i.e. n) how to make the "on" to be red while the rest of everything remains in black text. I have been trying to read up on sed and awk, but it is still pretty much a mystery to me right now. There will be other things in the output file that I wouldn't want a rogue "on" to be in red, so just the instances of "on" in that one chkconfig return.

I turned on my Acer laptop and during bootup it seemed normal. After it passed the blue Acer logo, all I could see is a black screen and a black cursor outlined in white in the shape of an X. Thinking it would be a one time thing, I turned it off again.it still was a black screen.

I was configuring the vnc server or remote desktop using the "gconf-editor" -- "desktop - gnome - remote_access" pane, and first I clicked on "disable background" to see if it was usefull or not to disable it (in terms of speed). It worked fine but sometimes when closing the connection, the background refuses to reenable, mantaining the black background...
That's ok, I decided to disable the feature and share via vnc the background as it is a wired net and I do not really need this feature.
My surprise is that now, whith the feature DISABLE (box unchecked), I cannot set a background, it is always black and I find no way to go back in this...
is this common, or something that can be "easily" fixed?

I do need to change or edit this white Ubuntu logo on the black background that comes right after GRUB and before my xsplash is played. How do I do that? Where is that picture saved in the system?
I have edited my xsplash the way I want it by changing the pictures in /usr/share/image/xsplash but cant find a way to edit this other bootup screen.

My G73JW works really great except for 1 thing. A change in the performance level causes short black flickering on the display, which is absolutely inacceptable (e.g. with compiz). Setting the preferred mode to "performance" locks the performance level and helps but seems like a bad solution (batter life and heat).

I use frequently on my laptop the "suspend" function of opensuse 11.2.
I would like to use the "suspend" function on my desktop too running an opensuse 11.1 with default kernel 2.6.27.39, but when I restart the machine the monitor is black and the only solution is to reboot it.
Is it possible to use the "suspend" on desktop? Where is it possible to get the information to make it possible?

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?

I installed Ubuntu 11.04 today as the main OS on my laptop.I had deleted my XP partition, and repartitioned it according to a guide I had found. (http:url)......Basically it was setup like this: 500mb ext2 primary partition, has the grub folder, I believe this is either the '/' partition, or the '/boot' partition 2gb swap space logical partition
10gb ext4 logical partition -- this is either the '/' or the '/boot', it contains the 'bin,boot,cdrom,dev' etc folders 243gb (the rest of my hard drive, with the exception of a partition that contains documents and files from my XP OS, formatted to NTFS) ext4, this is the one that has all my desktop/documents/etc folders.After Ubuntu was done installing, I had some message pop up about installing an ATI proprietary driver for my ATI graphics card (an ATI Radeon HD 4330, I believe, I may have messed that number up). I installed it and rebooted, no problem.
Next, I had another update window pop up with 198 items checked and ready to download and install. I went through all of this, and rebooted, again, no problem.Next thing I did was install some apps that were essential for me to have to use for my work (an ide, chat programs, etc). No problem with any of that.Last thing to install was the OSE Virtualbox, and then I installed WindowsXP Pro and Windows Vista Business, then installed the guest addition addon for VB. This all worked without any issues whatsoever.
Time goes on, and I notice my computer is heating up much more than (seemingly) normal. I begin to wonder if its my graphics card. So I shut down the computer and let it cool down. Reboot, and no problem, still working fine.Then I opened a couple of apps and tried a simple game (can't remember the name) I believe it was a simple 3d topdown, as I wanted to test my graphics card. This is where things seemed to start to go wrong. My laptop began hanging, not even allowing me to access the terminal via ctrl+alt+f2. The screen flashed and I saw the blue/green/grey fuzz that I get when the graphics card is starting to heat up too much. Then everything hangs and I can't do anything at all, including move the mouse. I did a hard reboot (I believe this is what you call pulling the plug/pressing the power button, correct me if I'm wrong). I then rebooted, saw a chkdisk, then it booted seemingly normal, but it hung right after the purple screen after the grub screen.
This is pretty much where I'm at right now. I strongly suspect the fault is with the ATI drivers, but have been completely unsuccessful in my attempts to fix it. I've googled just about everything I could think of, along with searching these forums. I've tried just about everything listed in the forums, but to no avail.I've tried the commands that are supposed to purge the ati drivers, but all I get are errors that say they can't remove the 'virtual drivers'.
Right now I'm booting off a live cd, so I know the computer still works fine, just not my actual installed OS. I'd really like to get the issue resolved without having to reinstall, as it took quite awhile just to get it usable in the first place, but this has already taken so much time, I may just resort to that if we can't solve it any other way. Got too much work to catch up on as it is.As a re-instated note, perhaps if you have any tips, but not particularly about fixing the OS, my laptop (I'm strongly guessing my graphics card) is heating up much more than normal, compared to that when XP was installed. Is this more than likely just a driver issue, as is the rest of it? Also, I did have Compiz installed, though I didn't choose for it to be installed, I believe it came pre-installed. I've heard it could cause some issues, though I have no idea as to the validity or relation to this particular issue.
Edit:
I just remembered while searching for a solution, I found a post somewhere that said something about the information not being sent to the monitor from the graphics card properly, thus no desktop. I'm guessing that'd still fall under the driver issues, but again, I'm unsure. I would think that wouldn't be entirely true anyway, since I can still see my mouse fine, just no desktop, only a black screen.

I have Ubuntu 10.04 running kernel .26 installed on my Dell Dimension 2350 with 512mb of memory. The problem I have been having is, When I am using the computer mostly Internet stuff for no reason the monitor will go black then on the screen it will be at a terminal screen, kind of like when you start up the computer, I don't remember what is all on it but the last thing in the list was: checking battery state: OK after that the screen will flash in multiple colors and then it goes into a loop of just black screen than a colorful flash and back over to a black screen. the only way I can fix that is by holding down the power button. this will happen mostly on face-book on the games and just on the profile page, but it does happen just checking my gmail or play solitaire it does this around 4-8 times a day.

This obnoxious bar has just appeared in Smplayer at the top of the screen. It stays there even when I go full screen. Now full screen isn't full screen and there are black edges on both sides of the screen. I have not be able to figure out how to hide it. I do not need or want this onscreen display. How can I configure Smplayer to make this go away? How can I get my 16:9 full screen aspect ratio back? I have done nothing to mplayer or smplayer as far as editing any or changing any configuration files. I tried several videos and it displays on all of them. It was not there last time I used Smplayer.

I have openSUSE 11.3 with an nvidia card connected with two monitors. In the past I used xinerama which was ok, but now I need to have two separate desktops, one on each screen. I set the nvidia driver with x screen, and now one screen works perfect and the other only shows a black screen. When I move the mouse over the black screen, the mouse pointer turns into an X, but moves correctly, which seems to me that the problem is that I need to set the second desktop to that screen. I looked on forums on how to do so, and no luck.
