When i turn on my monitor the screen goes blank, but the 'on' button is lit up. Any ideas of what the problem could be?edit: When i turn off and turn on my monitor, it displays what's on my computer for a couple of second and than the monitor turns off again.
View 7 RepliesI am running Debian 8.3, and I'm running Gnome 3.14.1.I have an external monitor plugged in with HDMI, and while Linux is loading both screens are on duplicate. Once the GUI kicks in, only the external screen works, so I have to enter my password blindly. Then, I open a terminal and run
Code: Select allsudo echo 950 > /sys/class/backlight/intel_backlight/brightness
and the laptop screen turns back on.
I'm wondering: Is there a way to streamline this so that it happens on boot, but after GNOME loads?Or: Is there a better method to solve this?
Last Thursday, 3/11, I installed a new mother board (ASUS M4A785TD-V EVO), AMD Athlon II X4 Processor, 4Gig DDR3 ram (RIP JAWS), 1 SATA DVD drive, along with my 2 IDE HDD's. The display was OK during BIOS review, and boot UNTIL it came to mounting x-graphics, at which point the screen went black, and a display message came up saying Out-of-RangeHf: 30KHz-70KHzVf: 50Hz-90HzCurrent Frequency:90.3KHz, 60.0Hz.
Does anyone know what is causing this? I mean, is there no way that Deb 5 X86 is going to run on a quad 64-bit system, or can something else be wrong? Before changing hardware, I had seen indications that this system was backward-compatible to older systems, and the more in depth study I've done since seems to verify this.y be, however, that I completely mis-understand what I am reading - this is all pretty new to me.
I tried booting into Debian 4, Libranet 3, and Linspire 6. They all complained loudly, but differently, about x being inoperable. I can't tell you how they complained because I can't go back and check them. THAT is because, in BIOS, I was testing the system with all the different options for "Internal Graphics", to see if one would work. One of these options was "Disabled". Oh-ho-ho! BAD MOVE!!! it's disabled, all right, including BIOS! I can't believe it. There was no warning, whatsoever. I assumed no engineer in his right mind would allow that option to lock out the BIOS without SOME kind of warning. I'm going to try to call ASUS tech support tomorrow to see if they have a solution, but if anyone knows how to reverse this, please let me know. I suppose the only answer is a separate graphics board. But I don't want to get that if I can't use this MotherBd.-processor setup.
The day started as usual until I got the very bright idea to install Ubuntu. A new OS along side W7, that sounded great. I checked some guides on the Internet, it was all very straight forward. Install it and Grub will show you the OS:es when you boot up. I installed Ubuntu, rebooted. After the BIOS messages the screen goes blank and my screen on-button begins to blink, as if trying to find a signal, I press enter, it reboots instantly. After BIOS messages I get to a screen that says "GRUB error: uknown filesystem grub rescue>"
I've looked through everything here and nothing works. I've tried to fix the mbr-thingy using Windows Repair and even though it says "one partition was updated with new boot-thingy" when I reboot, I get into that very same grub rescue. I think my setup has something to do with it. I run RAID0 (2x360Gb hard drives), first having C: at 50Gb and then the rest as F: for programs and such. What I did was that I shrunk the F: part and then used that as partition for Ubuntu. Also please have a look at these screenshots, my partitiontables and such seems completely wacky to the raid: Where should the boot-loader go? I'm very, very new at this. I've had Ubuntu Netbook remix on my netbook for a time but still treat me as an utter beginner.
how to turn off your laptop screen in Ubuntu using a script/command, but none seem to have worked for me except one.
after digging around, I found the following suggestions:
1. xset dpms force off or xset dpms force suspend
This didn't work for many people, nor did it work for me, as the monitor would just turn on again after a few seconds. The second other suggestion I found to make this "stick was:
2. sleep 1; xset dpms force off
or sleep 1; xset dpms force suspend
This worked for some people, by delaying the monitor off function by one second, but it did not work for me, as the monitor would turn on again by itself after one minute exactly. Maybe those who thought this was the solution just walked away and never really found out their monitor plays sneak-peak with them. The next solution i found digging around was supposed to really make the monitor stay powered off:
3. sleep 1; && xset dpms force off
or sleep 1; && xset dpms force suspend
But this didn't work either; what a disappointment, and it also made my CPU and HDD freak out for a while while my monitor was off. So after some more digging around, I came up with the following: (and I don't remember where i got this, whether it was from here or elsewhere on the internet, but if it is your creation, please contact me and I'll edit the post to give you credit)
4. create a file and save as something like Monitor_off.sh in a folder of your preference with the following in it:
---------------------------------------
#!/usr/bin/python
import time
import subprocess
from Xlib import X
[Code]....
Then just go to: System>Preferences>Keyboard Shortcuts and assign a Keyboard combination shortcut to call and initiate the script. I chose "<Ctrl>+M" because it's easy to remember.
Make sure to disable any same keyboard shortcuts you may have in Compiz to avoid conflicts.
This final script just worked perfectly for me. And the Monitor just stays off until I shake the mouse or press a key on the keyboard, and my CPU and HDD don't rev up like a Harley. This final solution seems to be working for everyone of my friends without a glitch.
I have installed Debian 8.0.0 64bit with KDE 4.14.2.I managed to install Skype. But the video call didn't work. Actually when I'm receiving a video call it works, but I cannot initiate a video call.Then I installed libv4l-0 package (which has been installed to /usr/lib/x86_64-linux-gnu/libv4l) and found here URL...) that I have to do something with this Code: Select allLD_PRELOAD=/usr/lib/i386-linux-gnu/libv4l/v4l1compat.so /usr/bin/skype in order to make video calling work. I went thought some results on google but I couldn't find any hint. Probably it's very simple to do with this I cannot get.

I (maybe somewhat rashly) tried to connect my tv to my laptop (Dell Latitude D400) running Ubuntu 9.10.
I plugged in the cable, went to the System>Display menu, where it had detected the model and make of tv (Samsung 19" LCD) (I think the resolution was 1650 x 1050 or similar). I clicked the box to activate the second monitor with the "Virtual resolution" adjusted. It told me to log out then log back in.
I accordingly logged out but then couldn't log back in. It had evidently changed the resolution not only on the 2nd monitor but also on the laptop monitor. A box was visible on screen but completely illegible/unclear since the laptop monitor couldn't display that resolution.
After a few restarts and button pushes it is now restarting at a terminal (I enter my username/password at a command prompt on an otherwise blank screen rather than the graphical interface loading up).
Question: are there any commands that could change the resolution back to its original settings then restart the Ubuntu graphic interface? Some thing similar to the "load with last known good configuration settings" option in Windows maybe.
I just replaced my PSU and now my computer is not booting up. To make sure that my new psu is not causing the problem, I put my old one back in but it still doesn't boot up. My system powers on, motherboard led glows, the processor starts running and so does the graphics card. The monitor stays blank though. Nothing shows up on the monitor. Just a blank screen with the monitor led blinking. What could be the problem ? It was working fine before I replaced my psu.

I installed Natty on it with the machine hooked up to a Samsung LCD with a 1680x1050 resolution over DVI. No problems at all. I want the box to pretty much output MP3s and web video, so I'm not needing much. When I take the box and hook it via DVI to my LCD, I get a blank screen on boot up. I try sticking the natty CD in it, and I get a blank screen trying to live boot it too. The LCD doesn't do 1680x1050, so I brought it back to my Samsung and set the default resolution to something nice and safe: 1280x1024. Still the same behavior. When I take splash mode off, I see a "load fallback graphics devices fail" error as it is booting up. Hard for me to think the driver is the fault here when it works on my over LCD just fine.
I have a new ubuntu 10.04 install, it is the third that I have done recently. On this particular install (unlike the others) the screen goes unexpectedly blank at seeming random intervals and any motion restores the screen. It is acting like a screen saver with the blank screen option set. My screensaver preferences are set to use a screen saver 'for a 7-minute idle period. The lock screen option is off. For AC power management never is chosen for "put computer to sleep" and 30 minutes is chosen for the "put display to sleep" option.
This is a compaq presario desktop.
I just installed ubuntu 10.10 did a clean install, formatting the previous ones. Install completed successfully, rebooted, entered in GRUB, chose linux, linux starts the my screen goes black, there is no signal coming to my monitor, linux runs fine though i think because I hear the ubuntu login drum. I press ctrl+alt+F1, but can't get to console either, the screen is looking for input signal. Should note the I have a Palit NVdia 9600GT gpu because I saw that people with NVdia card sometimes have similar problems.

At first attempt server started but after I changed a screen resolution the monitor went blank. I restarted a computer but after the X server started immediately the monitor wnet blank. I found that for completely for me unknown reasons Xorg was trying to use an NVIDIA glx module with radeon driver. I removed this nvidia driver, I expected ubuntu would be able automatically to set up a proper configuration, but instead of ubuntu complained about a missing driver. I also tried manually to set up some basic config using Xorg -configure but after that the Xorg server was stuck.

View 1 Replies View RelatedI have Lenny installed on an Imac G4, running command line only. It's primary purpose will be SSH.
I would like to know how I can turn off the screen when I'm not using it. It will be left on running other things for periods of time, and I want to save power. (and the screen)
Since the screen is built-in, it might have a similar solution to what I would do with a laptop. On the other hand, there are no shortcut keys to dim the screen like on a laptop.
Because it is command line mode only, I will need to know what commands to use to dim or shut off the screen, or to configure an auto-off time limit.
I initially installed Debian Lenny on my system but couldn't get sound to work so I upgraded to squeeze hoping that the newer kernel would somehow fix that. Unfortunately, the update caused the screen to flash on and off starting at the login screen - I'd get a split second with the screen on and then it would go off for a second or two. The boot screen still allows me to boot from Lenny's linux kernel, and that still works. I also had this problem when I installed ubuntu on this computer so after some searching around I remembered that adding radeon.modeset=0 as a boot option fixed this. Now the screen no longer flashes, but everything is really slow - I think that disabled graphics acceleration? After some searching around it seems that these problems are probably caused by something called KMS in newer linux kernels but I don't really know.
Anyway, does anyone have any ideas as to how I could turn on graphics acceleration again without having the screen flashing on and off? Or suggestions for making sound work? I think in the past (on ubuntu) I ended up having to enable the proprietary graphics driver, but on the other linux distros i've tried I used proprietary graphics and flash and my computer got slower and slower and started to crash, so I'd rather stick to the open source driver if possible - i don't need really need 3d acceleration. Stability is the reason I switched to debian. My computer is running Debian squeeze amd64, intel core 2 duo e8400, ati radeon 4830, 4 gigs of ram. relevant results from lspci: 00:1b.0 Audio device: Intel Corporation 82801JI (ICH10 Family) HD Audio Controller. 01:00.0 VGA compatible controller: ATI Technologies Inc RV770 LE [Radeon HD 4800 Series] 01:00.1 Audio device: ATI Technologies Inc HD48x0 audio maybe part of the audio problem is that there are two audio devices listed?
When I watch any video on YouTube my screen will turn off (no HDMI connection) and then it will turn on after a couple seconds (10 -40 seconds). When I played Borderlands 2 the screen is completely fine.

However, now when I suspend, and later hit a key on the keyboard (usually space) to resume, all I see is an illuminated black screen. I can't even open a tty via Ctrl+Alt+F1. I can however ssh into the machine.he only possibility I can think of is that I am no longer running kdm. I just use "startx" to star an openbox-session.
View 8 Replies View RelatedI have an system that d8.2 appears to install correctly. On first (or subsequent) boot, I get the DB8 load screen, then a quick fsck, then nothing. I appear to have some sort of environment running as I can move a mouse pointer, but nothing else.
CTRL-ALT-F2 results in the mouse pointer vanishing, but nothing else. I expected to end up at the CLI.
I have tried different installs and options, always the same result. This machine ran an earlier version with issues.
I have this machine (motherboard ITX Jetaway NF94-270-LF based on CPU Atom N270, full specs here) as a server for some time now (about 4 years). Debian 8.1 is installed on it.
Two days ago, after a power failure, the machine was not able to complete the boot process. I attached a keyboard and a monitor (on VGA port, the motherboard also as a DVI one, but I don't have a suitable monitor) to be able to see what's happening and interact with the machine. Unluckily, at a certain point during the booting sequence the screen goes blank and the monitor goes in standby mode; apart from that, the boot process continues in the background.
As far as I can recall, this behaviour existed for at least a couple of years (if not from the beginning) and the boot process was always completed successfully until two days ago.
The screen goes blank after the setup of the keyboard mapping. I tried everything to avoid the screen going blank: in the Grub menu I set the "vga" parameter, the "nomodeset" parameter, the grub_gfxmode parameter, I removed the "quiet" option, I removed the "load_video" line, I forced the BIOS to only use the VGA port for the video and so on, in order to disable or configure differently the video and the framebuffer. All these stuff had no effect at all: the screen keeps going blank at the same point during the boot process.
The only way I was able to use a fully booted system through keyboard and monitor was via the rescue mode of the Debian 8.1 netinst image. But that way, of course, I wasn't able to observe the normal boot process. So, I checked the boot parameters of the rescue mode and I found that the only usefull parameter was "vga", which I already used and was ineffective.
I have some problem with Debian 7. Just installed Debian 7 wheezy.
Motherboard Intel D2500CC, graphics - Intel GMA 3600. Monitor (BenQ V2200 Eco) connected via VGA cable. No X server installed.
After GRUB boot as soon as modesetting kicks in, the monitor loses the signal and goes black. Keyboard does appear to be active, as Ctl-Alt-Del will cause a reboot.
I tried nomodeset, vga=791, 771 etc kernel parameters, but this won't work.
I installed wheezy/LXDE yesterday in my HP netbook (first-time Debian user) and I am unable to get suspend/hibernate to work properly: after I come back all I get is a blank screen, although the computer seems responsive (CapsLock and such do respond).
I installed firmware-realtek from non-free (for rtl_nic/rtl8105e-1.fw, which was missing at install), nothing changed. I have acpi installed (it came by default). My graphics card is an Intel GMA 3650 (I see in internet that this is a problematic one). I just want a lightweight Linux to replace the default W7S.
I decided to update all the software on my computer. Fortunately, it upgraded kernel version 3.14 to 3.16. I was happy to learn that suspend now worked on my laptop by calling pm-suspend, but it did not worked by closing the lid. So I search and found on debian's website that installing systemd and adding some config lines in /etc/systemd/logind.conf would sove the issue. So I followed the procedure and did like instructed, to end up with a computer that boots on black screen.
The last verbrose line I see on boot up is "kvm disabled by bios" and then it shutdown down the screen. The computer works, as I can login and shutdown by doing those operation blindly.
I tried removing systemd but it still does not work. If I use the old kernel 3.14 I can boot without any problem, but if I use kernel 3.16, I boot to a black screen. I remember successfully booting in 3.16 before installing systemd.
I have just installed Debian 7.8.0 powerpc on my imac G3 (400Mhz, 256Mb Ram).

I searched Google and forund that if I ran ctrl+alt+f1 and logged in, then ran lspci, I could get the ID of the graphics. So I did, and:
