mac's questions

I am trying to disable the following extensions via tweak tool

https://extensions.gnome.org/extension/545/hide-top-bar/ https://extensions.gnome.org/extension/517/caffeine/

But its not working. They are being re-enabled automatically(when I reopen tweak tool, they are back). After disabling from tweak tool, I refreshed Gnome shell as well. Still they are getting enabled again. I tried with other extensions. Few are getting disabled and few aren't. What might be the issue ?

PS: Now even uninstalling isn't working. I tried various ways - removed from tweak took, deleted extensions manually from ~/.local/share/gnome-shell/extensions directory. They are getting uninstalled first and then system onreboot or back from standby I am getting numerous prompts asking "Install the extension" as if I am actually trying to install the extension and even when I click cancel, the extensions are getting installed again automatically in few sec/mins !!!!

Using Ubuntu Gnome 16.04, 3.20.4 shell version

I am using Ubuntu Gnome 14.10 64 bit on Dell Inspiron 3521. I have ATI Radeon 7560M HD Series Graphics Card. I tried installing ATI Graphics card in different ways.

1)Selecting fglrx from Additional Drivers under Software & Updates section

2)Selecting fglrx-updates from Additional Drivers under Software & Updates section

3)Downloaded latest ATI Driver (amd-catalyst-14-9-linux-x86-x86-64.zip) from AMD website and installed it.

Before trying every option, I uninstalled older drivers completely.

In every option, after reboot, all I got is a text console. Couldn't able to get into Display at all. Is there any driver working for Ubuntu Gnome 14.10 ? How can I get it and install it ?

The primary reason for me installing is the battery backup. Its hardy 40 mins on Ubuntu where as its 4+ hours on Windows. I want to install ATI Graphics card driver and disable the Discrete graphics card and enable only Intel graphics card so that battery back up will be better.

Please help. Thanks in Advance.

Update: This is the error I am getting

/usr/bin/X: symbol lookup error: /usr/lib/x86_64-linux-gnu/xorg/extra-modules/modules/extensions/libglx.so: undefined symbol: LoadExtension

Xinit: giving up

Xinit: unable to connect to X server: Connection refused

Xinit: server error

Update2 : Tried amd-catalyst-omega-14-12-linux-x86-x86-64.zip but no luck

I want to bookmarks files in Gedit so that I can open them easily later. There are some old plugins which used to work for older versions. But is there any working plugin for Gedit 3.12+.

I am using Gnome shell 3.10 on Ubuntu Gnome 14.04 . Gedit version is 3.12.2

Thanks

I am using FF 30 on Ubuntu 14.04. I installed flash and youtube is working fine. However some videos from some sites aren't playing - Foot ball videos (FIFA) and Cricket videos (Starsports) etc. Just black screen appears.

Same videos are working fine on Google chrome

Some links which I couldn't play on Firefox

I am running Ubuntu 13.10, Gnome shell - 3.10 on Dell Inspiron 3521 (bought almost one year ago). Initially it worked fine, but now laptop is suddenly freezing. Nothing works then, no mouse, no keyboard , no Ctrl+Alt+F1 or anything. The only option left is rebooting. What I observed is it usually happens on battery. Especially when I leave it off for a few minutes idle. I checked with Dell and got to know that it's not a hardware issue.

Has anyone else experienced the same?

Thanks!

I am building a small QT (C++) application where I ask user the software he want to install. Once he selected some packages a, b, c from the list all I have to do is run

sudo apt-get install a b c

One way of doing this is using Qprocess or System and run this command directly from C++. But I thought this would be a hack and wanted to do using apt-pkg C++ library. But sadly documentation is very sparse for this library :( I saw source codes of some similar softwares - Software updater ( apt-watch ) etc and found it too complex. Just to run above command, it has lot of code - Initializing pkgCacheFile, PkgIterator, pkgAcqArchive.

Do I have to do all this to run this simple command ? Isn't there a direct function which takes software name as argument and install it ? Where Can I get a sample working code for the same?

I am on Ubuntu 13.10 Gnome shell 3.10.I want to automatically restore tabs in gedit that were open in previous session (without any manual work) - Just like a web browser - FF/Chrome.

Any such compatible plugin ?

I have tried various solutions available online

1) Added pcie_aspm=force to /etc/default/grub

2) Since Jupiter is no longer available in 13.04 , installed tlp

But still fan is making lot of sound (its running very fast I guess) and temperatures are around 60c (and sometimes even increasing) even on normal load. But on windows8, its fine. I bought the laptop just a week ago.

Even battery is very bad in Ubuntu. It hardly lasts for 2 hours on normal usage (which lasts for around 4 hours for same usage in Windows). How can I improve battery performance ?

Please help.

I bought a new laptop - Dell Inspiron 3521 which came preloaded with windows 8 and GPT partitioning. As usual, My first step after buying a new laptop is to install Ubuntu.

Hence followed this guide - Installing Ubuntu Alongside a Pre-Installed Windows with UEFI and disabled secure boot (UEFI is still enabled) and installed Ubuntu 13.04

Now restarted my system. Now I don't see grub. When I selected F10 to enter boot options, I see both Ubuntu and Windows boot manager options. I am able to enter Windows but when i select Ubtuntu, it takes me to grub command line but not GUI. I even tried repairing with boot manager but still it didn't help. boot repair continues till some steps and fails saying - "Please close all your package managers and continue" . I have verified that there are no package managers running. But still it says the same. Here is my boot repair summary - http://paste.ubuntu.com/5779528/

I tried other ways as well but was not able to boot into Ubuntu.

Please help. Thanks

For gnome shell - a simple extension exists. Is there any similar extension for Unity as well?

I have Windows on my machine and then installed Ubuntu 12.04 using USB. I was not getting the option to boot into windows, so I ran boot-repair but still I am not getting option to boot into windows. What can be the issue ?

Edit: I have deleted my recovery partition (some 20GB) and installed Ubuntu on it.

It is disabled (greyed out) in Mouse and Touchpad settings. Edge scrolling works though :) Tried many solutions available online but couldn't succeed.

My touchpad is

SynPS/2 Synaptics TouchPad

First I should say I love gnome shell a lot. Its awesome and its notifications are too good . I can directly chat in them without even opening another window. But my only problem is it doesn't recognize smileys. It just displays them as simple text. But I love smileys a lot and I miss them :( Any idea how to enable them(I dont think we can enable them) and If not, any idea if its in road map of gnome shell ?

How do I increase the size of icons in the GNOME Shell Dash?

I have tried http://abhizweblog.blogspot.in/2011/06/gnome3-change-icon-size.html and tried changing the /usr/share/gnome-shell/js/ui/dash.js file as well, but it still didn't work.

In 12.04 Ambiance theme, the default right click menu color changed from black to white.

From this bug-report, it appears this decision is by design

But I love black only. How can I change it to black?

I have read in many blogs that old lock screen is replaced by new lock screen in Ubuntu 12.04

But when I installed 12.04 Beta 2 (and updated my system) , its still showing old lock screen. Any idea if its delayed ?

I have upgraded my gnome shell to 3.4 in Ubuntu 11.10 through

sudo add-apt-repository ppa:ricotz/testing 
sudo add-apt-repository ppa:gnome3-team/gnome3
sudo apt-get update && sudo apt-get dist-upgrade
sudo apt-get install gnome-shell

But it broke my system. Gnome shell is completely broken - When I login it just shows desktop wallpaper and nothing else.

And importantly Unity is also broken. Attaching the screenshot

Some main issues

1)Two menus are appearing now - Global menu as well as application menu
2)Icons on top-right panel are appearing weirdly
3)My Default Ambiance Theme also got screwed. Instead of black color menus, I am seeing white color menus.

How do I fix them? Or Do I have an option to revert back to original settings or will reinstalling Unity/Gnome Shell helps ?

In unity, I used to configure in ccsm. How do I do it in gnome-shell?

How do I make menus look transparent in Gnome-shell?

In unity, I use ubuntu-tweak to do this(In ubuntu tweak , Go to Desktop->Compiz settings and then select Enable transparent menus option). Since compiz is no longer being used in gnome-shell, this is not working any more . Any alternatives ?

I love gnome-shell but I am still missing some awesome features of compiz like "wobbly windows" and other desktop effects!

I am using Lenovo Thinkpad laptop with ATI Radeon HD 3400 Series graphic card. I installed Ubuntu 11.10 64 bit today and tried to install proprietary drivers

1)Hence I installed proprietary drivers displayed on my system (through jockey) .Rebooted my system. Performance is better now but Still compiz is not working.

2)Then I tried the second driver available - 'post-release-updates' but couldn't install due to some error. Hence I opened synaptic and installed fglrx-updates and rebooted my system. Not much change and still compiz didnt work

3)Removed all these packages and downloaded the latest driver from ATI http://support.amd.com/us/gpudownload/linux/Pages/radeon_linux.aspx?type=2.4.1&product=2.4.1.3.42&lang=English and installed it and rebooted my system. This is worse as I dnt get even launcher or dash this time - I guess I am forcefully logged in to Ubuntu 2-D . Still compiz is not working

Am I doing something silly here ? Is any one facing similar issues with ATI ? Please help Thanks.
