• Ubuntu 12.04 LTS - Black Screen at boot After changing Nvidia Driver

  - by nDman

  2 days ego i updated my Ubuntu 12.04 LTS to latest updates but i ignored Grub Updating because I thought it will clear my grub settings (I'm so noob!). After restart every things was right, the Ubuntu started normally and every things was working well except graphic which had problem before update. I had the experimental driver before but I changed it to the current-update version. After restart Ubuntu stock on black screen. I tried to reinstall Nvidia driver from recovery but it not worked. Then i used Update Grub in recovery, it not worked too but i see this line on screen at boot: at this time it stops and keyboard not working, but when I push the power button it shows these lines and it will shutdown. OK finally I made it start with older kernel (3.5.0-28-generic). Now how can I keep this kernel or fix Ubuntu to work with new kernel? Should I reinstall Nvidia driver? Which version should I use?

• Ethernet Wired Connection Help

  - by user107598

  I have recently installed Ubuntu 12.10 onto my Dell Inspiron N5010 and Ive been all over many forums trying to figure out how I can get my ethernet cable to be recognized so I can set up a wired connection. My Network Card is the Realtek RT8139 and from what Ive gathered the ethernet port driver for it is installed. Whenever I run ifconfig in the terminal it says that eth1 is up and running but no matter how I edit the connection I cannot get it to work. If anyone can help it would be greatly appreciated!

• Monitor flickering ATI

  - by Atzu

  I'm using ubuntu 12.10 on laptop samsung with randeon hd 6620g (APU A8), when I run amdcccle -version it says 2.18, not sure if that's the correct version. My problem is that I have and external monitor, AOC e2343Fsk and when I finally got it working at the resolution I want 1920x1080 it works fine for like 5minutes and then it starts flickering... I solved this on Windows (the exact same problem) with some options (I don't remember very well) I believe there were some buttons '+' and '-' on some vsync option I played with them on windows and Yay! got it working, but I don't see anything similar on this catalyst version (I used xorg-edgers ppa for installing fglrx). Thanks.

• No sound after clean install

  - by John Cheednik

  Did a clean install of Ubuntu 12.10 and everything working great except for the sound. Ubuntu doesn't even seem to be recognizing the fact my HP dv6000 has the capability of making sound! I have the dummy output problem, and when I try to open alsamixer using terminal I get the message that no such file or directory exists. I can't get it to recognize any soundcards or audio devices at all. I've been working on the problem for a couple days now and have even taken the laptop apart to ensure that all cables are properly attached... When I go into the PhoenixBIOS there are no sound options that I can find. The laptop does make a loud beep if I press buttons in the BIOS, but once it boots to the hard drive, the thing is mute. HELP!

• How can I get SLI working with 295.40?

  - by Steve

  I've been doing a lot of googling these last few hours and I'm not having much luck. Perhaps I don't know exactly what I am looking for. I just recently installed Ubuntu 12.04LTS x86_64. Looks beautiful! I have two GTX470's in SLI, and I am finally migrating my desktop over given the hopeful gaming support as of late. My laptop has been enjoying multiple distros of Ubuntu for a couple years now. However, new problems come with unexplored territory, here. At first, I only had one working monitor of my two. Over on nvidia-xconfig I fixed that, but the only solution that actually worked was twinview. Just recently I read here that twinview is not compatible with SLI. Sweet. When I try to tell it, oh hey, use a separate XScreen, configure it the way I want it, click save to configuration file, enter my password, then a sudo restart lightdm, it's broken. One screen blacks or whites out (Couldn't tell you the specific conditions for each, I'm dubious at this point,) and I get this huge error dialogue box upon login. Something about incompatible resolutions if I remember right. Though I am sure I set the resolutions for each screen correctly. Anyway, when I try to enable SLI (sudo nvidia-xconfig --sli=On) despite the fact it hates twinview, unity breaks. The sidebar is there, but only one screen works, the mouse is trapped running along the left edge of it, and the background of the sidebar is a solid blue. Anyway, this ended up being entirely too verbose, I'm sorry, but could anyone part some wisdom please? It would be appreciated!

• Help with Dial Up

  - by iSeth

  I am trying to set up a computer for my friend that has dial up. The problem is nothing I try can detect the modem. GnomePPP can't find it and I can't figure Kppp out. I've been looking all over the net on my ethernet trying to find an answer but I keep getting routed back here. I have also tried using scanModem and it finds something like Conexant Systems, Inc. HCF 56k Data/Fax/Voice Modem but the rest of it is really confusing. I've also tried this but I'm not very terminal savvy and it didn't work. It seems like I have to compile a driver but I don't know which one or how to do it. I have also tried multiple modems. Any help would be appreciated. Thanks EDIT: scanModem thinks the modem is disabled on startup. EDIT: I reinstalled Ubuntu but the problem persists.

• Graphics hardware warning when updating to 14.04

  - by pacomet

  As I use Ubuntu at work I just update only LTS versions but now I'm not sure if I can/should. As my computer is now ten years old I would change if was mine but as it is owned by my employer I have to work with it. It's not a bad one, it runs fine (this was not true when still had Windows on it ;-). When updating to 14.04, it warns about possible bad/slow performance with Unity 3D so I stop updating as I am at work, not my own computer. As I understand from http://askubuntu.com/a/438958/25305 Nvidia Geforce FX 5500 graphics card is still supported in 14.04. Now, in 12.04, I have driver version 173 and unity 2d runs fine for me. output of /usr/lib/nux/unity_support_test -p OpenGL vendor string: NVIDIA Corporation OpenGL renderer string: GeForce FX 5500/AGP/SSE2 OpenGL version string: 2.1.2 NVIDIA 173.14.39 Not software rendered: yes Not blacklisted: no GLX fbconfig: yes GLX texture from pixmap: yes GL npot or rect textures: yes GL vertex program: yes GL fragment program: yes GL vertex buffer object: yes GL framebuffer object: yes GL version is 1.4+: yes Unity 3D supported: no Should I update? Is it better to stay with 12.04? Thanks

  I have bought an Asus wireless LAN PC Card WL-100GE model, and I am using lubuntu on my system. While I have no cable connection, currently I cannot access the internet and update my laptop.

• Printing Off Center or Images Offset After Upgrade to 14.04 LTS (Brother HL-2240)

  - by fortitude

  :) I have a very frustrating problem with my Brother HL-2240 under Ubuntu 14.04. Bear in mind this was working perfectly under Ubuntu 13.10. In Firefox, when I print a webpage, all of the images are off center and cut off, this is a big deal for my work. In Google Chrome, when I print a webpage, the page is off center, toward the right margin. In Opera, when I print a webpage, all of the white areas within the margins are black, using a lot of toner. PDF opened in document viewer, prints off center. Steps I have taken to troubleshoot: 1) Playing with the printer settings, resetting to defaults, etc. 2) Un-installing the Brother driver and re-installing (linux-brprinter-installer-2.0.0-1 from the Brother website), which works perfectly in Ubuntu 13.10. I see a similar, un-answered question, here. Hopefully this question provides some additional clarity to the matter. If anyone would like some additional detail because she or he is willing to help, please let me know. I can scan output from the printer to show you. Thank you.

• Dell b1160w not working in 14.04

  - by mission007

  I originally installed the dell b1160w printer on ubuntu 12.04. It worked as expected. A few months ago I upgraded to ubuntu 14.04 and now I can't get the printer to work. I looked at the driver information on the dell site. They have not updated their driver since 2013 so 12.04 is the latest version with a supported driver. Is there a work around for this problem, like a generic driver that I can use or a way to install whatever printer interface ubuntu 12.04 was using? I have a windows virtual box. I can get it to work through there, but it's inconvenient to pull up my virtual box and transfer the files over to it anytime I want to print.

• Is it ok to run with unknown video device?

  - by JTex

  I'm new to linux and just starting to learn. From what I've read and experimented with there's no more support for older ati mobility cards. I resolved a few boot issues with my first install of Ubuntu 12.10(now on clean install #3) and my system seems to function ok with video unknown. Picture quality is good and no issues with video playback. It functions for my purposes. Should I leave it as is......or will this cause problems I'm not aware of? Thanks

• Install/Downgrade kernel to v3.5.5 on Ubuntu 13.04

  - by Villi Magg

  I've been looking around the internet for a solution to downgrade the kernel from 3.8 to 3.5.5 since I've got the AMD/Ati Radeon Mobility HD 5600 graphic card on my machine. This video card in unfortunately not supported by the 3.8 kernel. And then when I've downgraded the kernel I need to install a version 12.* of the AMD Catalyst driver. There is too much in stake to wipe out the current installation of the OS and install an older OS. So I would like to avoid doing that to the ends of the world. Hope someone can help me with this one? Kind regards! Villi Magg.

• Bumblebee optirun appears to depend on Intel

  - by user206398

  I have a Lenovo T420 with Intel and Nvidia graphics. On upgrade to Ubuntu Saucy, I had to purge and reinstall bumblebee-nvidia to get beyond optirun failing to find a GPU driver. Now, "optirun glxgears" and "optirun sol" succeed, but optirun fails on 2 Virtual Life viewers that it supported in the past, Cool VL (CoolVLViewer-1.26.8.34-Linux-x86) and Imprudence (Imprudence 1.4.0 beta2). In both cases, the error output is huge, but it starts with libGL error: failed to load driver: i965 and libGL error: failed to load driver: swrast From the little I can discover, i965 is an Intel graphics driver, which should not be invoked at all. I haven't found any information about swrast. I suspect that some of the X configuration associated with Bumblebee has some Intel dependence that is invoked on certain library calls, but not others. I haven't discovered any definite information on this line. The Cool VL Viewer runs without optirun, but complains about the insufficiency of the Intel graphics.

• Ubuntu 14.04LTS Ethernet Driver Needed for desktop

  - by 321sos

  I have just installed Ubuntu 14.04 and I need to install an Ethernet driver. When on windows 7 the machine used the Atheros AR8152 Ethernet driver. I have looked at other similar questions on this site, but the solutions never worked out for me as the solutions were mainly aimed towards laptops that had a wireless internet connection to retrieve updates. I cant find any driver packages for Linux so I really need some help. Thanks

  - by Aldo

  i have a dell N4110 laptop, and i want to know if the driver is installed and working well, something like the device manager in windows , or another way to know if a device is driverless or if the device might have a better driver, like my mousepad, in windows it have multi-touch gestures , that scrolls or zoom with two fingers (like an ipod) but in ubuntu it just works the right part as a scroll bar, so maybe it is installed one driver, but i need other one that uses well my devices. and the grphics card, i have not idea if it is well installed or isn't. i have a Intel 3000hd graphics card. thank you for your time. have a nice day people! =D

• Ubuntu 14.04 compiz thumbnails preview flicker

  - by HockeyBum

  Ubuntu 14.04.1 x64 (upgraded from 12.04) with Unity desktop Dell Latitude with NVIDIA GF119M (NVS 4200M) - Optimus is DISABLED Using NVIDIA legacy binary driver 304.117 When I set the CCSM option to allow thumbnail previews, the thumbnail 'flickers' for about 1 second before the actual thumbnail image is displayed. I don't think I had this enabled under 12.04 so not sure if it's version-specific. Should I be using a different driver (there are newer ones - Ubu shows NVIDIA binary driver 331.38 and the non-proprietary nouveau, plus NVIDIA has newer ones at the site)? TIA!

• Reverse-Engineer Driver for Backlit Keyboard

  - by user87847

  Here's my situation: I recently purchased a Sager NP9170 (same as the Clevo P170EM) and it has a multi-colored, backlit keyboard. Under Windows 7, you can launch an app that allows you to change the color of the backlighting to any of a handful of colors (blue, green, red, etc). I want that same functionality under Linux. I haven't been able to find any software that does this, so I guess I'm going to have to write it myself. I'm a programmer by trade, but I've haven't done much low level programming, and I've certainly never written a device driver, so I was wondering if anyone could answer these two questions: 1) Is there any software already out there that does this sort of thing? I've looked fairly thoroughly but haven't found anything applicable. 2) Where would I start in trying to reverse engineer this sort of thing? Any useful articles, tutorials, books that might help? And just to clarify: The backlighting already works, that's not the problem. I just want to be able to change the color of the backlighting. This functionality is supported by the hardware. The laptop came with windows software that does this and I want the same functionality in Linux. I am willing to write this software myself, I just want to know the best way to go about it. Thanks!

• Is it possible to use binary nvidia driver with GeForce 7300 SE?

  - by jrennie

  I have an Nvidia GeForce 7300 SE. It worked fine with the nvidia driver when I was using 10.10. When I upgraded to 12.04, the (nvidia-current) binary driver failed---I couldn't even get a login screen. The "nouveau" driver works okay, but the display is quite sluggish. I've read about the fact that my GeForce is blacklisted (here and here). But, when I tried the suggested workaround of using nvidia-173, I discovered that it wouldn't install because of a failed dependency: xorg-video-abi-10 (Package not available). The "precise" nvidia-173 package page notes this (dependency bug?) So, my real question: is there a GeForce 7300 SE workaround for 12.04?

• System update and now no wireless connection in Ubuntu 10.04

  - by Alphaeuphemia

  I'm running an older version of Ubuntu (10.04), and updated yesterday through the update manager. The system informed me I needed to restart, so I did, then immediately shut down the system and went to work. When I rebooted later in the evening, I couldn't connect to my wireless router. I could find my connection and had the passcode and all that usual business, but could this be a kernel or driver issue caused by the update? If so, how can I fix it? I've attempted to go through the troubleshooter, but to no avail. Additionally, I put off upgrading to the next stage of Ubuntu for so long that I can no longer prompt the system to ask me if I'd like to. Any way to change this?
