I just realized a bug that exists in 17.2 (Mint, Cinnamon) remains in 17.3: When I close the lid of my Dell Precision laptop, the screen remains on. When I open the lid, then the computer goes into sleep mode. This is the equivalent of Wyle E. Coyote's parachute opening a second after he has slammed into the desert floor.

 

That must be a Cinnamon bug, not a linux bug. I run Linux Mint 17.2 KDE and there's no such bug here.

@Michel: how about in Cinnamon 2.6.13? The issue is present there as well?

Thank you, @John Sutherland ! This is exactly what I've been looking for! Your help is very much appreciated. Cheers!

 

Mint still uses Firefox 43.0.0 on my side allthough there is Firefox 43.0.3. I tried to use a manually installed 43.0.3 directly from Mozilla, but it refuses to work with Flash. I even tried to use the freshplayerplugin, so that Firefox can use Chromes Flash, but it doesn't work at all allthough the plugins are showing up inside Firefox.

Any ideas?

Edit: I tried 32 and 64bit versions.

Edit2: Flash stinks, but I need it for Twitch. :-/

 

If it helps, I stopped using FF and switched to Pale Moon. Since then, no issues with anything browser related and all my add-ons work perfectly.

 

Speed Up Firefox mouse scrolling in Linux Mint. This also works in Pale Moon browser.

To speed up mouse scrolling speed in Firefox in Linux Mint. Also makes scrolling smoother and less jumpy.
(may also work in Firefox in other Linux distros, I haven't tested that, however.)

In the Firefox URL field type,
about:config
and press Enter.

In the Search field type,
mouse


Double-click on...

mousewheel_system_scroll_override_on_root_content.enabled, default, boolean, false

to toggle it to true.

The line will now be displayed as:
mousewheel_system_scroll_override_on_root_content.enabled, user set , boolean, true

Click on the Firefox top menu
Edit, Preferences,

Click on
Advanced, General

Make sure
[X] Use Smooth Scrolling
is checked.

This speeds up my mouse scrolling considerably in Firefox.

 

The screen brightness slider in the Power Manager applet of Linux Mint 17.3 'Rosa' Cinnamon didn't adjust the screen brightness on my Dell Inspiron 17r 5737 laptop. The laptop uses Intel HD 4000 graphics.

I was able to get the screen brightness slider and the f4 & f5 keyboard screen brightness adjustments to work by creating the following script. This solution should work for other laptops that use Intel HD 4000 graphics.

Using a text editor, create a file with the following script:
(You will have to perform the following functions as root.)

Code:

Section "Device"
    Identifier  "Intel Graphics"
    Driver      "intel"
    Option      "AccelMethod"     "sna"
    Option      "Backlight"       "intel_backlight" # use your backlight that works  here
    BusID       "PCI:0:2:0"
EndSection

Give the file this name:

Code:

80-backlight.conf

Save the file in the following folder:

Code:

/usr/share/X11/xorg.conf.d

Log out and back in or restart Linux.

The screen brightness slider in the Power Manager applet should now work.

 

I'm using Linux Mint KDE 17.3 x64 and default it comes with kernel 3.19. I've tried to upgrade to 4.3.3, but it doesn't get along at all with my ATi video card, messed up my installation, thus I had to reinstall.
Kernel 4.4 LTS, released 2 days ago, should have better support for my ATi, so I wanted to install it using the following commands:

$ cd /tmp
$ wget \
kernel.ubuntu.com/~kernel-ppa/mainline/v4.4-wily/linux-headers-4.4.0-040400_4.4.0-040400.201601101930_all.deb \

Install the Kernel:

$ sudo dpkg -i linux-headers-4.4*.deb linux-image-4.4*.deb

Unfortunately, the installation part went...weird. Here's the log:

I've also downloaded the 3 *.deb files individually from Ubuntu Wily repository, copied them in /tmp, but the errors were the same. Anyone had any luck upgrading to 4.4 without problems?

 

I have Linux Mint Cinnamon 17.3 x64, but I'm not clear if it's KDE or xfce. My video card is nvidia in a Dell M4700 laptop. If I tried it, would the results (positive or negative) be of value to you?

It's all backed up with Acronis, so no problem if it blows up. Even if it did blow up, I can do a clean install in way less time than any Win OS.

 

Did it. I guess it worked. When I run 'uname -r' in the terminal, it returns with:

"4.4.0-040400-generic"

Hope this helps.

 

Mine is at version 3.16.0-38-generic. If I upgrade it will it break the system (not backed up)? Cinnamon x64 17.3 version.

 

Right now the score is tied at 1. The OP's broke, mine didn't. We need a tie breaker

It's your decision to take the risk. I never did ask what is so great about the latest kernel, and I don't notice anything obvious.

BTW - I had a little trouble with the script file. Could well be my fault, but I couldn't get the single 'wget' command to grab all three packages at once. I did 'wget' three times, once for each package.
