Recently in the ubuntu12.04 study python,python2.7 python3.2 difference is quite big, just want to learn the newer
After upgrade
Results appear input method does not show Update-manager and add-apt-repository can not be used, Android emulator also can not open.
The culprit until Python
Because python3.2 is not compatible, it causes the 2.7 version of the feature to be unusable before upgrading from python2.7 to 3.2 many dependencies
How to solve the problem of Python upgrade please http://book.51cto.com/art/201405/439867.htm
to get to the bottom, how to solve the problem?
Fglrxinfo
X Error of failed request:badrequest (invalid request code or no such operation)
Major opcode of failed request:136 (GLX)
Minor opcode of failed request:19 (x_glxqueryserverstring)
Serial Number of failed Request:12
Current serial number in output stream:12
A preparatory work:
1. Download the latest graphics driver for you
Http://ati.amd.com/support/driver.html
Recommended Download Amd-catalyst-14-4-rev2-linux-x86-x86-64-may6.zip
2. Before installing, execute the following command to install dependencies.
sudo apt-get install build-essential cdbs fakeroot dh-make debhelper debconf libstdc++6 dkms libqtgui4 wget execstack libe Lfg0 dh-modaliases
Second, remove the previous ATI drive and Mesa Drive. You may not have installed it, but if you do not remove the existing graphics driver, it may cause the module to load and drive errors after installation, not normal drive
Remove previous ATI drivers and Mesa drivers. Perhaps you did not install, but if you do not remove the existing video card driver, may cause the installation after the module and driver errors, not normal driver.
If you have previously installed the driver manually, you need to perform the following two lines, if not, skip.
cd/usr/share/ati/
sudo./fglrx-uninstall.sh [Note there is a problem here, if the directory is not fglrx-uninstall.sh what to do, I have encountered this problem, tossing the will, later in the download of that file Fglrx-14.10.1006.1001/driver/found a shell]
sudo sh fglrx-uninstall.sh--force "Note add--force otherwise you will be prompted to delete"
sudo apt-get remove Xorg-driver-fglrx xserver-xorg-video-ati XSERVER-XGL
Third, install the driver, do not install before the delete step, or it will be uninstalled. There is nothing difficult, basically the next step is OK.
Unzip the first step of the ATI driver download
The directory after the CD decompression
sudo sh./amd-driver-installer-14.10.1006.1001-x86.x86_64.run
Follow the prompts next
Four, installation completed according to the prompt restart
Five, check the installation effect
1, first look at the driver information is correct, execute
Fglrxinfo
The following is my result
Display:: 0.0 screen:0
OpenGL Vendor string:advanced Micro Devices, Inc.
OpenGL renderer string:amd Radeon HD 7400M Series
OpenGL version string:4.4.12874 compatibility profile Context 14.10.1006.1001
The key is to have ATI, can not be other, if not, the driver module does not load correctly, you need to according to the contents of the display, the corresponding driver deleted.
2. See if your video card works in XV mode and executes
Xvinfo
If it shows a lot of results, it's working in XV mode. If the display looks like this, then you need to set the
X-video Extension Version 2.2
Screen #0
No adaptors Present
Set XV mode manually
sudo aticonfig--overlay-type=xv
3. See other information
Glxinfo | grep Direct
And my result is
Direct Rendering:yes
4, test the speed and work is normal, the program will show the rotation of the gears and some values.
Glxgears
Fgl_glxgears
