Brightness notification control is not working on Ubuntu 14.04. I searched over google if there is any method to fix it but I can't find nothing which is working or reliable.
This is what I got from /sys/class/backlight/
acpi_video0 acpi_video1 intel_backlight radeon_bl1

How do I get my Broadcom BCM4313 working correctly?
Just installed a fresh Ubuntu 12.10 64bit on my laptop, run the update manager, restarted and suddenly I can't use my wifi anymore.
Ubuntu software center installed automatically the wifi additional driver as you can see in my screenshot.
If I mark the option "Do not use the device" and apply changes, restarting Ubuntu my wifi is back and I can use it.
If I run iwconfig my terminal is showing this 
Now if I use Ubuntu for more than 20 minutes surfing the web my wifi it keeps to be connected but I don't receive any signal from it. Any page I try to open it simply don't open (just waiting icon). If I disconnect my wifi and connect it again, same issue, it doesn't work. The only way to make it work again is to restart Ubuntu. And the same story it happens again after aprox. 20, 30 minutes.
WIFI device details: 03:00.0 Network controller [0280]: Broadcom Corporation BCM4313 802.11b/g/n Wireless LAN Controller [14e4:4727] (rev 01)

Still having this problem on Ubuntu 12.10 Touchpad twitchy on an HP G62 with a SynPS/2 Synaptics TouchPad even after I upgraded to 12.10.
Same problem here posted 2 days ago Touchpad sensitivity
I really have no idea what the problem is and why they didn't fix it. Using this OS less and less 'cause of this. Great OS but synaptics su kc s.
I removed my Windows OS and now I want to resize my /home partition with that unallocated space. The main problem is that the free space is not under my sda4. How to move it there and then resize my /home partition?
I just removed windows from my laptop completely. I will install it on virtual box. My question is now, how and from where do I edit the boot options to boot directly in Ubuntu after I open my laptop without passing through the boot options page or if this is not possible, how do I remove the Windows boot line from there?
Everything is working fine till the end on installation where Ubuntu stuck on ubuntu ubiquity: Processing triggers for update-notifier-common.
Waited for more than 10 minutes and nothing, It stuck there.

After I installed Ubuntu 12.04 got some issues with my touchpad.
I reported the problem and finally today a guy replied here - https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-input-synaptics/+bug/992330
It seems that the solution was good because I edited HorizHysteresis and VertHysteresis using synclient:
synclient VertHysteresis=48 and synclient HorizHysteresis=48
To see if they were really edited I run into terminal
synclient and just seen there the values I added. Everything is running perfectly till now. But after I restarted Ubuntu the values are gone and rolled back to default.
A guy told me to edit the xorg.conf file but there is no xorg.conf file in etc/X11.
Thanks and hope someone can give me a good solution.
Just installed 12.04 LTS and I experience some problems with my touchpad. Everytime I tap/double tap, the cursor is moving around (not static as should be). For example if I want to close a window, I click on "x" button from touchpad, the cursor is moving and not always hit the "x" button. Touchpad buttons left click, right click are working well, but tap not. Did u guys experience the same problem? Is there something related to sensitivity? How to fix it?
PS: on Ubuntu 11.10 didn't had this issue
