• Nvidia Powermizer Performance Levels

  - by jeffrey

  Is there anyway to configure Nvidia Powerimizer performance levels? My current setup has 3 power levels with the lowest one being 50mhz. The problem with this it that it lags compiz when it goes to the lowest performance level 0. Minimizing, maximizing, dragging windows, etc. are all sluggish when it's at the lowest level. Once powermizer leaves level 0 everything is very smooth and runs great. Is there anyway for me to remove level 0 and just run Level the two higher levels 1/2? I don't want to complete disable powermizer, but I can't stand the lagging once powermizer goes into performance level 0. Setting the option "prefer maximum performance" fixes the problem as it disables powermizer, but the GPU is overkill at stock speeds for most desktop use @ 850mhz. intel i5 2500k asus gene-z z68 evga 560ti fpb (driver 295.40) ubuntu 12.04 LTS x64

• Ubuntu display - no existent

  - by Patrick M

  My HP Pavillion Dv5 1004nr worked great with Ubuntu up until 11.04. Now, ever since Unity desktop environment the display has been sporadic at best. I was told that the video driver bugs (known and largely ignored) were fixed for the ATI raedon card in my laptop with 13.04. So I installed it. 13.04 doesn't even detect the display. Boots to black screen every time now. Is there ever going to be a fix for the AMD architecture with ATI raedon chipsets? do the developers even care? this has been an issue for years, and no sign of a fix in sight....

• Low display resolution under Ubuntu 12.04

  - by Chinouk

  I had some problem after installing new drivers for Nvidia. After having followed the instructions answered to this question, I now only have the Nouveau open-source driver. I can have access to my desktop, but I'm stuck with a 640x480 (4:3) resolution. No other resolution is proposed in the dropdown list of the "Displays" utility. I tried installing the two Nvidia drivers suggested in the "Additional Drivers" utility, but each one broke my display again. Now that I have reverted back to Nouveau again, what should I do to get a higher resolution ?

• 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?

• Ubuntu 12.04 wireless detected, but can't connect to 128-bit WEP enabled microsoft MS-700 base station

  - by ubuntufan

  I installed Ubuntu 12.04 on a Presario R 3000. The Wireless card was not detected (firmware missing). Based on several related posts, I downloaded and installed the b43 driver and wireless was finally enabled. However, I am unable to connect to my base station successfully. The base station is configured for WEP 128-bit. I tried both infrastructure mode and ad-hoc mode (with the channel, band, etc. configured). Appreciate any help in trying to get past this.

• What do I need to do when installing old version of ubuntu on new arch platform?

  - by Blangero

  I got a board with aptio cpu which is said to be of new platform and may have driver problems while using old version of ubuntu, and it do have. After installing my customized Live ubuntu server with X(the system runs as a liveCD), X starts but failed to get right resolution. If I run ubiquity in the live system to install the system to my disk, I can't start X and the whole console was a mess.Tried connect from ssh and upgrade, failed to solve the problem. Install ubuntu 12.04.2 desktop, at bootup the text was a mess, X starts and still could not get the right resolution. Install ubuntu 14.04 server, at bootup the text was also a mess, but it turned clear and the resolution is right. So what else do I need to provide? CPUInfo ? lspci -nn | grep VGA ? anything else? And what's the problem? What can I do to support the newest arch in my customized system? Thanks

• Unable to use separate X-Screen's GTX 550ti Ubuntu 12.10

  - by user12622

  I am currently trying to get from "Twin View" to using separate X screen's on Ubuntu 12.10, however I'm not having a great deal of luck. I am using an Nvidia GeForce GTX 550 Ti and am on driver version 304.51 Initially, when I turn on the separate X screens option, presents me on the 1 monitor with a box to accept the changes, however the 2nd screen goes black, and effectively, Ubuntu only seems to recognise the one screen. When I reboot, I boots back into Ubuntu with both screens working in Twinview. I'm not too sure where to start, but my xrandr can be found: Xrandr Any help is greatly appreciated, this is the last but one thing I need to make Ubuntu my only OS, so fingers crossed we can crack it :)

• DRIconf in Ubuntu 64x plus ATI GPU or something more?

  - by Balask

  I've been trying to get Call of Duty 2 to work in Wine in Ubuntu. It gives me a black screen. So I tried the fix suggested by the wine apphq and downloaded DRIconf. Funny thing is that it can't find my direct rendering device. "Could not detect any configurable direct-rendering capable devices. DRIconf will be started in expert mode" When I enter into it in Expert Mode is just errors out anyway. fglrxinfo gives me: display: :0 screen: 0 OpenGL vendor string: Advanced Micro Devices, Inc. OpenGL renderer string: ATI Mobility Radeon HD 4200 Series OpenGL version string: 3.3.11627 Compatibility Profile Context That shows me my driver is installed correctl,y right? World of Goo which is Linux native and requires direct rendering works like a charm. So I'm wondering, is there some other workaround? Is there a bigger issue? Does me running 64-bit affect it at all?

• Resolution problems

  - by tampe125

  i'm having some troubles with screen resolution. First of all, i'm using a Lenovo Thinkpad E520, with BackTrack 5 R2 installed. As far as I know, BT is based on Ubuntu 3.2, so I hope this is the right place to ask for help. My natural resolution is 1366x768, but I'm stuck with 1024x768. This is my hardware: lspci | grep VGA 00:02.0 VGA compatible controller: Interl Corporation 2nd Generation Core Processor Family Integrated Graphics Controller (rev 09) How can I fix that? Is there a ready-to-use driver or I have to compile that from source? At least, is there a solution, at all? :(

• How does a linked library combined with the main executable program file interact with a kernel?

  - by I ask Questions For a Reason

  I was attempting to find an answer to this, and I did to some degree, but definitely not anywhere good enough to form a respectable, sensible and clear answer. If I am using Windows, Mac, Linux, or nearly any modern made OS for desktop IBM-compatible PCs, laptops, even tablets and smartphones, there's virtual memory. Clearly, compiling, at least on Windows I know this, an executable object file, such as a simple C "Hello World" output to a terminal, will be linked with the standard library, and several other Window's system software, dynamic linked libraries, and the like. However, how does linking all of these executables together or resources form a connectable interaction with, say, a device driver or any other stuff on the lower level?

• ASUS VX-6 Laptop Wireless not connecting

  - by user2152790

  Someone posted a script a couple days ago, here is my output.Pastebin I can see wifi SSIDs in network, but cannot connect to mine. The only time wifi worked on 13.10 was in the Live CD, but wifi stopped working as soon as install process started. Did below but made no difference. sudo apt-get install bcmwl-kernel-source sudo modprobe -rv brcmsmac sudo modprobe -v wl What I do next? I tried Software&Updates and it showed 1 proprietary driver in use. This sounds like a WPA/WPA2 issue? Wifi works when I tried Zorin OS 7.1, wifi always worked in windows 7.

• Desktop in Kubuntu lacks bars and quite everything after trying to apply Plymouth fix for proprietary drivers

  - by Michcioperz

  I'm running Kubuntu 13.10, my computer's graphics card is Nvidia GT 520. I tried to fix that Plymouth's problem with proprietary graphics driver using an old script I found on the internet (it was coded for Natty, now that I think about it I shouldn't have done it). I ran that script and rebooted my computer. First incorrect behaviour I noticed was that Plymouth only displayed its text splash only on 1/4th of the screen, though when I pressed Esc key the logs were displaying correctly. Main problem appeared when I logged in. All my desktop's windows lack menu bar, can't be closed with Alt-F4, and they don't appear on the task bar. I tried fixing it by reinstalling GRUB a few times, purging /etc/grub.d and /boot/grub, but only the text splash issue was fixed. How can I fix that?

• Cannot shutdown, computer freezes

  - by Firouziam

  I've installed Ubuntu 12.04 (near windows 7) on my laptop(Dell studio xps 1640 with Ati Radeon HD 3670) and everything is working fine, but when I want to shutdown my computer it freezes! I don't know what to do after that, then I have to use power button to power off the computer and it's not good at all. I don't know what's the problem and I don't know how to figure this out. I installed the graphic card driver (12.6 version) from ATI website and it fixed my problem with playing videos but I think after that this shutdown problem appears! Would you tell me what's the problem and how can I fix it?

  This is what I am trying to do. I downloaded the latest driver for my VGA from http://www.nvidia.com. The installation needs the X11 to be shut down, so I log out of my account, then press CTRL+ALT+F1, then log in with my username and password, then run the command sh NVIDIA-Linux-x86_64-285.05.09.run in every possible way, I have even tried CHMODing the package with 777 permissions, but still I'm getting the sh: can't open NVIDIA-Linux-x86_64-285.05.09.run error. Any help would be greatly appreciated.
