Hello, I need some help. #Linux   #Ubuntu  
I wrongly type "sudo chmod -R 777 /usr/lib" in the terminal and now the command "sudo" cannot be used any more.
What should I do? How do I recover it to the originality?
This is the os in my own computer, not on my vps.

The best idea that I can think of is to simply reinstall every package, so all program files and libs are essentially "reset".

I have a puzzle now. When I open my google chrome under linux and enter the chrome://gpu, the followings is showed.
Driver Bug Workarounds
clear_alpha_in_readpixels
clear_uniforms_before_first_program_use
set_texture_filter_before_generating_mipmap
I think these problems can be solved even though they don't bring two much trouble to me with these bugs. I still want to know how to solve those bugs to make google chrome run more perfectly under Linux. More suggestions are needed.

Hello, I need some suggestions about this. 
I have a computer installed with Ubuntu and Win7, however, I want to try to install another Linux distribution in my hard drive. I try to minimize one of the Linux partition but it says that I need to create a logical partition. I can't find a way to create a logical partition in the Gparted tool, so what should I do? I am a little puzzled now.

If you only want to try stuff, I recommend using VMs. It's very fast and easy to torrent an image, load it, and run it full screen for a while. I wouldn't do anything on my hard drive until I'm fairly sure I'm sticking with a distro.

Hello, guys. I have a problem about the chromium browser, is someone here knowing how to solve the problem?

When I open my chromium browser from the terminal, the terminal shows:
libGL error: open uki failed (Operation not permitted)
libGL error: reverting to (slow) indirect rendering
The performance of chromium browser is very poor. When I open a new tab, the browser is laggy.
I try to Google it and find several posts about the problem, https://forums.mageia.org/en/viewtopic.php?t=7022&p=45147, I had thought this one maybe be of great help but at last it didn't give the final solution. 

The error is the same when I run it from the terminal:

+Alexander Diana I find that when I open chromium browser the graphics is lag, very very lagged. The computer fan is howling when I open more tabs. I can't see it whether the CPU load go up or not, but I think it should. As to the last question, I think it has something to do with direct rendering under Linux from the terminal.

Hello, is there some tactics to know which component should be installed from the winetricks or other places under wine environment to make the Windows game run more fluently in Linux ? Need some experience to share. 

Usually, I directly start the window game from the wine and some games can run without installing some components, but it is not always feasible. Some games or windows programs need some component to run, the first thought comes to my mind is that I consult the WineHQ database or find some articles about the method of wining windows programs or just try to run it in wine to test it whether the program can run or not. The most impressing game under wine environment is creed assassin series games. I install the game under wine and it can't work, but after installing some component from the winetricks and the game can run under it.

+Luke Larris PlayOnLinux is indeed a better way to manage wine version and configure wine. I have used it for some time, but not all the game scripts are included in the PlayOnLinux support windows programs list.

Forgive me if I reduplicate my previous post and I really want to know how to do it, I open my google chrome browser under Linux, enter chrome://gpu and the following message is showed. 

Driver Bug Workarounds
clear_alpha_in_readpixels
clear_uniforms_before_first_program_use
set_texture_filter_before_generating_mipmap

The three workarounds show. I want to know how to use these three workarounds to solve the bugs. Though I have googled it before, I am still puzzled.

You don't have to do anything.  That's the list of workaround that are already included in your Chrome.

Hello, I need some suggestions. 
I have a Android phone. Sometimes someone will send me some important texts and I want to save some texts to some cloud services, not all the texts anyway. I wonder whether  there are some apps which can function like this can both run on Linux platform and Android platform  or not.

Another puzzle. Today when I browse the Linux amd driver Pages, I find a doubt about that. 
http://support.amd.com/en-us/kb-articles/Pages/AMDCatalyst14-4LINReleaseNotes.aspx
When I pay attention to the System Requirements Line, out of curiosity, I want to know how to check the version of Xorg/Xserver and glibc and whether the requirement that POSIX Shared Memory (/dev/shm) support is required for 3D applications is meeted or not.

Though previously I just check the distribution version and install the LInux amd catalyst package from the distro without any problems. This is my curiosity.

Hello, is there someone who come across the problem like this?
I have been using Google Chrome for a long time under Linux, but recently I find the UI of Google Chrome is very slower than the previous version of Google Chrome under Linux. Does anyone meet with the situation before? I am using the AMD graphic cards and also enable the Override software rendering list in chrome://flags.

720p worked for my integrated HD 4250 and use Firefox when Chrome does not work well and vice versa.

Also as I do not play every day use open source drivers, better for 2d than AMD blobs, except the days I played some game

If I find a bug on amd linux catalyst driver, where can I report the bug?

Apology:
 I apologize that I have posted three posts owing to the network problem from my android phone. I have deleted the other two posts.
