• Unable to ssh in Beagle Bone Black

  - by SamuraiT

  I wanted to install pip onto beagle bone black,and I tried this: /usr/bin/ntpdate -b -s -u pool.ntp.org opkg update && opkg install python-pip python-setuptools then, it threw errors,but Unfortunately, I didn't log that errors. it was occurred a week ago and was't solved yet. I wanted to solve it now and I tried connect by ssh,but I failed. When I ping to beagle bone, it responds, and Cloud9 IDE is working too but not ssh. I don't think this is serious problem since I can connect to beagle bone by other methods: Cloud9 or so. However, to use python on beagle bone, I need to connect by ssh. Before trying to update and install python-pip, I could connect by ssh. Do you have any ideas to solve this connection problem? note I use default OS: Angstrom I don't use SD card. HOST PC is mac, OS.X 10.9 connect by USB serial I checked this but this wasn't helpful http://stackoverflow.com/questions/19233516/cannot-connect-to-beagle-bone-black I could connect by GateOne SSH client, but still unable to connect from terminal.

• Screen randomly goes blue/black/white

  - by FubsyGamer

  Problem Randomly, while using my computer, the monitor goes dark grey/almost black, or it goes white with faint grey vertical lines, or it goes blue with black vertical lines. It's as if the computer powers off. People tell me I sign out of Skype, Spotify stops playing when it happens, etc. When I look at the tower, it doesn't seem like it's off at all. Nothing changes, fans are spinning, lights are on, etc. If you were only looking at the tower, you'd never know there was a problem The only way I can get it to come back up is to push and hold the power button and turn it off, then back on This never happens while I'm playing video games. I've done 5-6 hour sessions of League of Legends, and it doesn't do anything When I'm just browsing the web, reading email, checking Reddit, etc, it happens all the time. It can happen multiple times in a session, it usually takes only about 5 minutes from the time I start browsing to when the computer crashes This started happening after I moved to a new apartment (this has to be relevant somehow, it was not happening where I lived before) There is nothing in the crash logs or event logs System Specs i5 2500k CPU AMD Radeon 6800 GPU Gigabyte z68a-d3h-b3 motherboard WD VelociRaptor 1 TB HDD Screenshots Device manager About screen Things I have tried I was getting a WMI Error in my event logs, but I fixed it using Microsoft's fix, KB 2545227 I was using Windows 8. I wiped the HDD and downgraded to Windows 7 64 bit I took out the video card and used a can of air to totally clean out the video card, all fans, and the inside of the computer in general. I made sure all of the video card pins were fine, then reconnected it I tried to update my motherboard BIOS, but anything I downloaded from Gigabyte was only for 32 bit machines, not 64. I don't even know how to tell what my motherboard BIOS is at right now I am using a power strip, and anything else connected to it works just fine If I re-seat the monitor cable while this is happening, nothing changes Please, help me. I've been battling this for several weeks now, and it's so frustrating it makes me not even want to use the computer.

• imageconvolution leaves black dot in the upper left corner

  - by Peter O.

  I'm trying to sharp resized images using this code: imageconvolution($imageResource, array( array( -1, -1, -1 ), array( -1, 16, -1 ), array( -1, -1, -1 ), ), 8, 0); When the transparent PNG image is sharpened, using code above, it appears with a black dot in the upper left corner (I have tried different convolution kernels, but the result is the same). After resizing the image looked OK. 1st image is the original one 2nd image is the sharpened one EDIT: What am I going wrong? I'm using the color retrieved from pixel. $color = imagecolorat($imageResource, 0, 0); imageconvolution($imageResource, array( array( -1, -1, -1 ), array( -1, 16, -1 ), array( -1, -1, -1 ), ), 8, 0); imagesetpixel($imageResource, 0, 0, $color); Is imagecolorat the right function? Or is the position correct? EDIT2: I have changed coordinates, but still no luck. I've check the transparency given by imagecolorat (according to this post). This is the dump: array(4) { red => 0 green => 0 blue => 0 alpha => 127 } Alpha 127 = 100% transparent. Those zeroes might cause the problem...

• Acer Aspire blank screen

  - by Gerep

  I'm using Ubuntu 11.04 Natty and when I installed it I had a problem with blank screen on startup and found a solution but I have the same problem when it is inactive and goes blank screen, it won't come back, so I have to restart. Any ideas? Thanks in advance for any help. This is what solved my first problem: When you start editing the /etc/rc.local and add before exit 0: setpci -s 00:02.0 F4.B=00 Edit /etc/default/grub, edit the line GRUB_CMDLINE_LINUX_DEFAULT: GRUB_CMDLINE_LINUX_DEFAULT = "quiet splash acpi_osi = Linux" Update grub with: sudo update-grub2

• Unable to get screen signal after purge FGLRX

  - by Boris

  I thought that my ATI driver was not running well so I wanted to re-instal it completely. I did: sudo apt-get remove --purge fglrx* sudo apt-get remove --purge xserver-xorg-video-ati xserver-xorg-video-radeon and after a boot I wanted to intal the ATI driver BUT at the boot no more signal to my screen. Since, every time I turn on my PC it gets to purple screen and then screen shuts down ! Note that: Even if the screen is off, PC seems to be running almost well: I m still able to use my network to access data shared with NFS. Using live USB I have no screen problem. I tried to plug my screen on an alternative output but it did not work. I tried CTRL+ALT+F1 while being on purple screen but it does not do anything, screen shut down anyway. I m going to try the SHIFT thing and learn from blackscreen wiki...

• Why does my Ubuntu freeze in the middle of something with a blank screen?

  - by mohamed

  I am facing a serious problem as my Dell Optiplex 745 loaded with Ubuntu 12.04 32bit freezes with a blank screen no mouse cursor no keyboard activity in many occasions. Sometimes when I open firefox, or software center, I really can't tell what the main problem is, but what i am certain about is it i have to do a hard reset to reboot. I tried to use a live-cd to boot but it did the same, tried the recovery console but couldn't find a way to fix from there (I am a new user) suspected a hardware problem but windows runs flawlessly so I believe its something related to ubuntu. Specs: Intel Celeron D 3.06 GHZ 3.0 GB ram Intel built in graphics Q965 1 TB HDD Bios Phoenex 2.6.4 Please help I really love ubuntu and I don't want to go back to windows!

• Screen is very dim on an Acer Aspire 6920Z

  - by Justin

  I've been trying to figure this out for a week now, my laptops screen is on and working but you cannot see whats on the screen without shining a flashlight at it. I'm using a spare monitor by the VGA port right now to be able to use this laptop, which is kinda a pain. Been reading around a bit about this problem and it seems to be a common-ish problem it seems. I've tried to change the brightness which doesn't help whats so ever. It just happen one day after I turned off the laptop for the night. The screen flashes on for a bit at start up, then goes completely dim. Anyone with this problem and find a fix? You can search up this computers spec by the name/model in the title if you need hardware info. I never had this problem with the old Ubuntu 10.04.

• nvidia GT 525m no screen found

  - by Pavan

  I'm a Dell XPS user with nvidia GT 525M with Optimus. When I installed nvidia I was greeted with blank screen. And the error in nvidia log was "Fatal error : No screen found". So after searching for the solutions I figured that I have to insert "BusID" in xorg.conf file. After rebooting I was again greeted with blank screen with error "Fatal error : screen already occupied". I don't what exactly the problem is. Do I need to blacklist Intel inbuilt graphics to nvidia in my machine or anything else needs to be done? Please guide me.

• How to totaly remove blank screen screensaver?

  - by Xamidovic

  I have no screensaver installed but when I watch movies after a while blank screen comes and I have to get up every time and move mouse to continue watching the movie. It really pisses me off. I found this command "gsettings set org.gnome.desktop.screensaver idle-activation-enabled false" which allegedly disables blank screen... I put that command in once, and blank screen keeps doing its crap. I did it again, blank screen still works on its own and would not stop. Did it trice, and nothing. Please someone help me with this, I'm freaking out when trying to watch a decent movie. I'd have to mention that I once had "xscreensaver" installed but I removed it after awhile. Don't know if it has something to do with blank screen still work, maybe some else would know. PLEASE HELP !

• Unable to install 12.10 on asus r500v

  - by bmdr38

  I have been unable to get beyond the grub boot screen of the live dvd/usb. The Try Ubuntu without installing, Install Ubuntu, etc menu shows, and I have tried adding/replacing nomodeset and no splash with neither helping. Even "Check disc for defects" does not display anything when selected. I am at a complete loss as to how to fix this one. I have had many successful installs in the past, but this is definitely a first for me. Just as FYI, Gfx card: Geforce GT 635M I realize this particular card has Optimus on it, however even the alternative boot/command line install fails to load. Any help would be appreciated. I realize there have been multiple threads on this, but none of the methods within them have solved this yet. Thanks

• Thinkpad W510 with default graphics drivers shows weird brightness issues

  - by Chantz

  Hey guys, I am currently running 10.10 - 32 bit on a new Thinkpad W510 with nVidia Quadro FX 880M graphics card. I am running with the default graphics drivers that installed with ubuntu install. My problem is that when I am logging in the screen acts normally as far as birghtness is concerned. I can increase/decrease brightness with Fn keys. But few seconds after I log in screen goes pitch dark. Hitting Fn+Home flickers the screen to all the way bright, then all the way dark. This behavior continues until I reach maximum brightness, in which case the screen stays all the way bright, for a few more seconds and then again goes dark if there is no activity & the cycle continues. Have you guys faced any of these issues? If so any pointers on how to resolve it. I am not alone, on ubuntu forum I saw another person having the same issue - link but no solution. Please help! UPDATE I followed the instructions that htorque mentions in his answer and it worked.

• Ubuntu does not recognize my built-in monitor.

  - by B3tturTh3nU

  I've recently discovered of a boot problem Ubuntu has with my laptop. I have successfully installed Ubuntu on two other computers, and I've never experienced this problem. What happens is, after the live boot CD loads, the screen goes completely blank. Although, I suspected that there was no problem booting, so I loaded with BIOS only, which worked perfectly fine. Of course, not being very proficient with this, I have no idea what needs to be done to fix the problem. I have switchable graphics cards(the ATI Mobility Radeon HD 5650, and some low-end Intel card), and an Intel i5 quad core processor. I was booting with the Ubuntu 10.10 64 bit desktop distribution. If there's any more information you need from me, please let me know. EDIT: I was able to look into this a bit more, thanks to one of the comments provided, and I have some new information. Ubuntu does seem to be able to recognize both of my graphics cards. The problem I found was that, in the Xorg.0 log, it mentions that there were "no screens found." I'm using a notebook, so the screen is built in. Does anyone know of a way to get Ubuntu to recognize the monitor?

• Blank Screen on 12.04

  - by stupidwhiteguy

  Can hit Ctrl-Alt-F1 and login but no fixes work. Tried nomodeset and everything else appears to have upgraded but can't see anything. I really need this computer to work. It is an old Dell with 1.6 processor with old school monitor. I don't know why people are giving my question negative votes. If you know how to fix this, then please help me, as I have read and tried all the solutions that I've found. Just for the record reformatting is not fixing it, and I can't get a boot CD to load either. If you know how to use the blank screen fix tutorial, please explain cos I'm lost. Most people don't understand this stuff and an easy "how-to" fix would be nice.

• Why is my Quicktime plugin transport bar black?

  - by TheDeeno

  For some reason when watching quicktime moves in firefox the transport bar is completely black. I can still use it to fast forward and rewind but I can't actually see any of the buttons. Any clue how to fix this? I've updated to the latest version of quicktime but it didn't help. I've also verified that this behavior is the same in both firefox and chrome.

• wire colors: color vs black vs white (positive vs negative voltage)

  - by David Oneill

  I'm working on building a computer (first time for me). There are several plugs that I need to connect to the motherboard (Power LED, reset switch, etc). Of the two wires, they are either: Color and white (reset switch, power LED, HDD LED) red and black (speaker, power switch) The manual for the motherboard has a nice diagram of where to plug them in, but has them labeled + or -. Which colors are positive, and which are negative?

  - by Vidar

  The following are all Windows 7 64 bit Business edition computers. I have a PC (lets call it "PC1") that I remotely access now and again using Remote Desktop Connection (RDC) on my laptop downstairs. Sometimes when I physically go back to sit at PC1, the screen is black and there is no way for me to wake it into life, no login screen or anything - the PC is still on and I am always forced to do a hard reboot. What can I do to stop this happening, it's really annoying.
