• Library and several small programs that use it: how should I structure my git repository?

  - by Dan

  I have some code that uses a library that I and others frequently modify (usually only by adding functions and methods). We each keep a local fork of the library for our own use. I also have a lot of small "driver" programs (~100 lines) that use the library and are used exclusively by me. Currently, I have both the driver programs and the library in the same repository, because I frequently make changes to both that are logically connected (adding a function to the library and then calling it). I'd like to merge my fork of the library with my co-workers' forks, but I don't want the driver programs to be part of the merged library. What's the best way to organize the git repositories for a large, shared library that needs to be merged frequently and a number of small programs that have changes that are connected to changes in the library?

  After upgrading to precise my audio is stuttering. It is happening, in VLC, mplayer, and anything streaming from the internet.

• How do I rotate my monitor using xorg?

• Update drivers for TL-WN851ND

  - by Tony_GPR

  Today I bought a new PCI wireless card, TP-Link WN851ND, with Atheros AR9227 chipset. It has 2 antennas and is compatible with Wifi N so I thought it would improve the quality of the signal. But after install it on my computer the result is the opposite to expected. It doesn't connect to my network, while my old Wifi BG card connect without problems, I created an access point from my smartphone to try the card, and work, but is very slow loading pages. In Windows 7 works perfectly, so I think the problem is the driver. I have Ubuntu 12.04 LTS with kernel 3.2.0.31, is there a way to update the driver or I can apply a patch to improve the performance of the card? Otherwise, anyone know if there is a work in progress to improve compatibility with this chipset, or is it better to change the card and buy one with better driver compatibility. And finally, which wireless N compatible chipsets have good support under Linux/Ubuntu?

• Confused with X.ORG version number

  - by caligula

  There is my trouble: I'm trying to install ATI drivers on my Dell Vostro 3350 laptop. On the AMD's site I followed steps to determine which driver should I use. After selecting what hardware I use I got a link to download amd-driver-installer-12-3-x86.x86_64.run and below was a description of that driver that it was compatible with X.Org version from 6.7 to 7.6. And I do not know what version of X.Org my Ubuntu uses. Cause after googling I found that version is 7.6 in Ubuntu 11.10. But after typing: X -version I got the output: X.Org X Server 1.10.4 Release Date: 2011-08-19 X Protocol Version 11, Revision 0 So what is the exact version of X.Org in Ubuntu 11.10 and how should one reliably determine it? Can anyone construe? Thanks.

• Keyboard freezes when xorg crashes

  - by gsedej

  Situation is like that. Many times has happened that Xorg freezes and with it also keyboard. Quite some times because of some Compiz effects or Flash (fullscreen switch). Keyboard becomes totaly unresponsive, while mouse still works (I can move cursor, but can't click since desktop freezes) and music still plays and I can connect trough ssh. This is the only way I know I can try to solve problem - either by killing browser&flash or lastly restarting xorg server. This problem appears on more than one Ubuntu computer. My home dekstop with proprietery nvidia driver, on my work where I use noveau driever (opensource driver for geforce) and sometimes (but rarely) also on laptop with ATI graphics (using r300g driver which is really good!). Can someone explains why mouse still works while I can't input from keyboard? (I can't switch to virtual console or do R-E-I-S-U-B command) I have USB keyboard and USB mouse.

• How do I get my RTL8192ce based wireless device working properly?

  - by JonnyTruelove

  I am using the rtl8192cu chipset (on a Belkin wireless USB adapter N300) combined with 64 bit architecture and the 3.8 kernel. Some of you may know that this doesn't work. I tried this fix - RTL8188CU USB Network Adaptor on ubuntu 13.04 and now my internet is super slow. I am totally new to Ubuntu and I am concerned I do not have the right driver. The "stock" driver was the RTL8192cu, but it didn't connect 99% of the time and if it did the upload speed was higher than the download. Right now I am connecting through my laptop with a crossover cable, so my internet connection is just fine in my apartment. Relevant output from lsusb is here: Bus 002 Device 002: ID 050d:2103 Belkin Components F7D2102 802.11n N300 Micro Wireless Adapter v3000 [Realtek RTL8192CU] (bonus question: is that [050d:2103] the actual physical address straight from the hardware? Or does it change when I put different drivers on it? I am concerned I do not have the right driver)

• 12.10 Unity doesn't appear when using Nvidia drivers

  - by Torben Gundtofte-Bruun

  I've just installed 12.10 from scratch. Unity also started okay, but in a poor resolution. I found a setting (I think it was in "software sources") to change the display driver to Nvidia, and then I rebooted. When Ubuntu now starts, it goes to the desktop (I see a file that I saved to the desktop) but there are no other screen elements -- no Unity, no menu bar at the top, no window decoration, nothing. Ctrl-Alt-T and Ctrl-Alt-F2 work as they should, but it's kinda limiting... How can I restore the default driver? I guess I need a way to open those "software sources" settings again - or anything else that could fix it! I hope I don't have to type all this by hand. How can I install a proper Nvidia driver so that I can get up to 1280x1024? My old tricks don't seem to work, but perhaps they might if I solve #1...

• Do Nvidia's drivers work in 12.10?

  - by Pratyush Nalam

  I recently upgraded to 12.10 and was just checking for proprietary drivers to be installed. I found this in software sources When I enabled Nvidia binary Xorg driver, unity disappears along with the launcher and everything. I just have the wallpaper. I did manage to open the terminal and open software sources and select the nouveau display driver which fixed it. Question is how to enable NVIDIA binary Xorg driver and have everything working? Hardware: Apple MacBook Pro 9,1 Mid 2012 15 inch non-retina. NVIDIA GeForce GT650M EDIT: I tried the solution here. And now, when I boot into Ubuntu, I get a blinking cursor. That's all! No tty1, nothing. help !!

• How do I get a title or some text to appear in a Silverlight mediaplayer when switching to FullScree

  - by Matt

  I am working on an ASP.NET website with VB.NET code-behind. I have a Silverlight mediaplayer object on one of the pages and the user may view that video in FullScreen mode. When changing to full-screen mode they are losing the title and chapter of the video series they are viewing. I have tried accessing properties and searched the web for examples on how I could put a title or some text over the player when in FullScreen mode to give the user an indication of where they are currently at while viewing each video. I am using OnClientMediaEnded to move through the videos after each video has ended so they are able to watch the whole series once in FullScreen mode. I am using a call to javascript in with this method to do that and want to know if there is any way to get a title or text up there and then change once the video switches to the next in the series? The controls on the player also go away when going into FullScreen mode so any help with that would be greatly appreciated as well. Thanks

• 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!

• Is NTFS-3G safe for writing?

  - by katrmr

  These days, I have to use the NTFS-3G driver to write to an NTFS drive (which will later be used in Windows). But I still remember the olde times of Linux ntfs driver which clearly said in the docs: 'If you write to an ntfs volume, run our special program afterwards which will clean up the damage done.' So, I read through the man, the docs, the Tuxera site and Askubuntu and found no discussion of the write-safety of NTFS-3G. The only thing that was mentioned somewhere is that the driver doesn't support the NTFS journal. So, the question is, can I use NTFS-3G and be sure that I will later read what I have written to the files? Won't, for example, Windows find the journal entries missing and 'clean up' the data according to its own faulty understanding?

• Problem installing NVIDIA-Linux-x86-302.07.run in 12.04

  - by paj100

  I have a catch 22 problem in trying to install this driver (NVIDIA-Linux-x86-302.07.run) to set my screen to its native resolution of 1280x1024 (hpL1906). Problem is that in order to install this driver, I need to stop the XServer but when I do this (sudo service lightdm stop), my screen goes blank and displays the message - Out of Range 1280X1024 need to reset (or something similar) - and I can go no further. So, I cannot install NVIDIA-Linux-x86-302.07.run without stopping lightdm but when I do so, I can no longer see anything on the screen or go further to install the driver that would let me adjust the resolution. Any advice on getting out of this loop would be greatly appreciated.

• embed multiple youtube videos to chromeless player cue

  - by Quaze

  So in the project ive been working on i use the youtube API to add a video to a chromeless player (got custom buttons, everything works no problems). It loads the youtube id which it gets from the database (Codeigniter, PHP). But what i would like to see is: instead of loading 1 video, id like to add all the videos i get from the database in the cue of that one player. So only one screen, first video retrieved from dbase gets played first, when its done second get loaded preferably also looped. Is there any way i can achieve this? My first guess would be to save the array with youtube id's somewhere and on state change (when the 'video stop'-event gets fired) load the next id from the array. Havent tried this yet because id prefer if the cue gets just gets filled on the init, so it doesnt have to load after a video has been ended. Is This possible?

• Black screen on Ubuntu 12.04

  - by user1648371

  I've just upgraded to Ubuntu 12.04 and I'm experiencing some problems. The first thing I noticed is that when I click the Workspace switcher all I get is a black screen (I can guess where the different workspaces are located and clicked on them, not a practical solution though). In addition when I lock the screen or suspend the laptop (a Vaio VPCEB4M1E) I get a shifted screen (I see the right most vertical stripe on the left size of the monitor and nothing about all the rest, to put it clearly I can see the gear that allows me to turn the pc off, etc, but not much more..) when I go to the additional driver menu I see the "ATI/AMD proprietary FGLRX graphics driver" are installed and the post-release update version is available. I don't know if the problem is driver related, so before doing anything I'd like to get some suggestions from you guys. Thanks you!

• poor font rendering in browsers on 12.04

  - by Alecs

  I'm using a Lenovo B570e. I've installed the mesa-utils for the graphic driver because it wasn't recognized by default. Now I have this: graphic card : Intel® Sandybridge Mobile x86/MMX/SSE2. I don't know if it's just my impression but I think all the images are a little bit pixelated and I think it have something to do with the drivers. Maybe is not the correct driver associated with it, I'm saying this because when I was on Windows 7 the name of the driver was something like " Intel hd graphics..." Any suggestions? Thank you! Later edit: This seems to happen only in browsers.

• nVidia GT 220 not working properly with Ubuntu 12.10

  - by Glaedr

  I used to enable proprietary nVidia drivers on every previous Ubuntu release to get it working properly (elseway I was forced to a very low resolution and no graphic acceleration), and everything worked fine then. In particular, I noticed - still I don't know why - that the GPU fan on every OS gets noisy until the video drivers are loaded (runlevel 5, it seems, in Linux), and then slows down to a normal speed. Today I installed 12.10. Running the Live CD, surprisingly, everything was working fine: full resolution, acceleration, silent fan, and so on. The running driver was nvidia-current (GT 216). After installing and booting I found that the fan was overrunning. The installed driver is nouveau. I tried installing nvidia-current, or any other proprietary driver, even installing the kernel headers & source and then the drivers (as suggested here), but all I'm getting with proprietary drivers is, the irony, low resolution, noisy fan and no acceleration (thus obviously unity and compiz refusing to start). Does anybody know a way out?

• amixer volume controls applies twice

  - by user214604

  The volume increment or decrement is happening double the intended amount using amixer for my alsa driver using ./amixer -c 0 set Master 1- command. This happens becuase by default volume controls apply for both playback and capture moduels. My alsa driver config doesnt enabled any of the capture controls. even there is no capture enabled, the function from simple_none.c returns true for capture channel. All the capture volume controls are applied to my playback driver. static int is_ops(snd_mixer_elem_t *elem, int dir, int cmd, int val) case SM_OPS_IS_CHANNEL: return (unsigned int) val < s-str[dir].channels; ./amixer -c 0 set Master Playback 10+ ./amixer -c 0 set Master Playback 10 - ./amixer -c 0 set Master Capture 10+ ./amixer -c 0 set Master Capture 10 - I suspect capture is enabled by default in my system for alsa drivers.
