Screen Flickering

I recently installed elementaryOS and everything was working fine until I changed the drivers in the Additional Drivers section.
I then tried changing back to the drivers previously used and others but to no avail. I can see the menu bar at the top and run applications, but the whole desktop just appears black.

Here is some info.

Code:

How can I fix this issue?

The most recent info on this card is about 10 years old.

The story is that I had an old dying PC with a vast accumulation of dust, causing sparks to fly.
I transferred the disk & wireless card across to a "known good PC" - and "amazingly" it worked.

This lasted for about a week.
OS is Xubuntu 12.04 and recommended updates of an unknown nature were applied from repositories & PPA's (not by me).

Soon after, wireless on the ancient Netgear wg311t PCI card failed.
I've tried moving it to a different slot - still does not work.
I've tried booting up from a Xubuntu 14.04.2 DVD - still does not work.
The two slots give slightly different results to the command Code:

dmesg | grep ath5k

First slot Code:

[   63.714417] ath5k 0000:05:06.0: registered as 'phy0'

[   63.733482] ath5k: probe of 0000:05:06.0 failed with error -5

Second slot Code:

[   13.594943] ath5k 0000:05:08.0: registered as 'phy0'

I'm prepared to buy a replacement card - so long as it is cheap!

Hello,

I have recently installed Elementary OS on my HP 550 laptop. While everything is running as expected, I've run into a small problem when attempting to watch videos on Youtube using Chromium.

The video loads fine but displays little yellow rectangles all over the video. According to Youtube, Chromium uses HTML5 rather than Flash - maybe that is the issue - but I am thinking it maybe a graphics driver issue. The videos run absolutely fine on Firefox and will stick to that if necessary, but I would prefer to use Chromium.

I have tried using Code:

gksu jockey-gtk

and it couldnt find any drivers to install.

This Code:

lspci | grep VGA

says:
Code:

00:02.0 VGA compatible controller: Intel Corporation Mobile GME965/GLE960 Integrated Graphics Controller (rev 0c)

Many Thanks

Hello,
know anybody how to delete that error at the end of dmesg?
If was not here before I installed the fglrx instead of the radeon driver.

I'm trying to underclock my netbook's CPU (Intel Atom D2500) in order to save some precious energy.

I tried using the cpufreq utility. However, cpufreq-info yields the following output:

Code:

analyzing CPU 0:
  no or unknown cpufreq driver is active on this CPU
  maximum transition latency: 0.00 ms.
analyzing CPU 1:
  no or unknown cpufreq driver is active on this CPU
  maximum transition latency: 0.00 ms.

So I tried sudo modprobe acpi-cpufreq and other combinations as suggested elsewhere. Loading these modules usually yields

Code:

ERROR: could not insert 'acpi_cpufreq': No such device

So I thought the BIOS doesn't allow scaling. Its configuration is very limited, though, and I couldn't find anything related.

My BIOS is the following (sudo dmidecode):

Code:

I am totally new to Linux. However, considering the many advantages of the operationg comparing to other OS, i have decided to go ahead with using MINT Rebacca which is the latest version. Initially for some time i did not have any issues in getting my internet connecton. However, for the last one week I am unable to connect through. The results of various terminal commands i applied is given below with a sincere trust somebody would be there to help me out.

Hello everyone.
I have just installed debian stable non-free onto my hard drive but the sound isn't working.

I've been to the debian site https://wiki.debian.org/SoundConfiguration and found that 'users' don't automatically have access to audio (for security reasons).
So I did the following command as root (sudo):
Code:

adduser USER_NAME audio

Now when I am 'user', I can get sound.

I also did:
Code:

chgrp cdrom /dev/sr0
adduser USER_ID cdrom

This allows 'user' to get sound from the cdrom.

I then went onto the debian soundfaq https://wiki.debian.org/SoundFAQ

From the 'lspci -v' command, I get these 2 outputs which have the word 'audio' in it:
Code:

01:05.1 Audio device: Advanced Micro Devices [AMD] nee ATI RS880 HDMI Audio [Radeon HD 4200 Series]
	Subsystem: Giga-byte Technology Device 960f
	Flags: bus master, fast devsel, latency 0, IRQ 19
	Memory at fdefc000 (32-bit, non-prefetchable) [size=16K]
	Capabilities: [50] Power Management version 3
	Capabilities: [a0] MSI: Enable- Count=1/1 Maskable- 64bit+
	Kernel driver in use: snd_hda_intel

00:14.2 Audio device: Advanced Micro Devices [AMD] nee ATI SBx00 Azalia (Intel HDA) (rev 40)
	Subsystem: Giga-byte Technology Device a102
	Flags: bus master, slow devsel, latency 32, IRQ 16
	Memory at fe024000 (64-bit, non-prefetchable) [size=16K]
	Capabilities: [50] Power Management version 2
	Kernel driver in use: snd_hda_intel

So I have 2 sound cards.

The debian website says: 'If sound does not work for root account as well, then that means that either your sound card is not supported by Debian or it was not configured properly'.

Ok, so the first part of the statement is worrying.
So I went to the debian device driver check page http://kmuto.jp/debian/hcl/ and did 'lspci -n'.
The output can be pasted onto their web page and debian will say if the sound cards are supported.
The web page shows that the sound cards are supported:

Quote:
10024383 Yes Advanced Micro Devices [AMD] nee ATI SBx00 Azalia (Intel HDA) snd-hda-intel v2.6.25
10029715 Yes Advanced Micro Devices [AMD] nee ATI RS880 [Radeon HD 4250] radeon v2.6.35-
1002970f Yes Advanced Micro Devices [AMD] nee ATI RS880 HDMI Audio [Radeon HD 4200 Series] snd-hda-intel v2.6.27-
So now I'm guessing that my sound cards are 'not configured properly'. But I've run a Youtube video and then changed the sound cards under alsamixer and I still don't get sound.
Is there is a simple solution to this please? Thank you in advance.

For whatever reason, when I try to mount a data DVD I get the following message:

Unable to mount [disk name]
Error mounting: mount exited with exit code 1: helper failed with:
mount: mount point /media/cdrom does not exist

Yet, if I put a DVD video in I can play on any of my video apps, yet I also can't mount those in a file browser. I have no idea what has caused this. I haven't backed up data to disks in a long time, I only did so today because I'm running low on space in one of my drives.

I was told elsewhere that I needed to alter a file: /etc/udev/rules.d/70-persistent-cd.rules

But I have no idea how to do this, and what I found there does not look like what was shown. This is what my file looks like:

Code:

# This file maintains persistent names for CD/DVD reader and writer devices.
# See udev(7) for syntax.
#
# Entries are automatically added by the 75-cd-aliases-generator.rules
# file; however you are also free to add your own entries provided you

Any suggestions would be appreciated.

Hello,
I am a long time Windows user. When XP got old I was like everyone else. Left with what to do. I purchased copies of Win 7 & got those working ok. I am just so tired of Microsoft products. So I took some time & I have read and researched several articles about Linux, Ubuntu, Zorin et al. Earlier this week I loaded a new Zorin OS9 from a DVD into a HP Compaq nx9420. The install worked flawlessly. Damn it is such an easy product to use. Bravo! I have an issue that has been experienced by many newbies. I found several answers to this same question. I read through several replies and went into terminal and typed in the directions. I am still stumped. I need some assistance. I hope someone has the time. I cannot connect to the internet through wireless.

The laptop has a Intel PRO Wireless 3945ABG Wireless network card.

I typed in:

Code:
dmesg | grep iwl

Here is the reply:

Hi folks,

after googling for a couple of days, I get the feeling, this is a common problem. But the usual fix doesn't seem to work for me.

I am trying to install Linux on a separate partition of my Acer Aspire V5-573G. I used the Lili USB Creator to make a bootable USB drive with Ubuntu 12.04 on it.

when I reach the installation menu, it doesn't matter what I choose (start live, install..), my notebook will always freeze on a black screen.

I figured out how to add 'nomodeset' to the grub line. This does bring me one step further (the Ubuntu start screen) but then I get this message:

Code:

ubuntu@ubuntu:^^$ [   20.267422] mei 0000:00:16.0: init hw failure. 
[   20.267558] mei 0000:00:16.0: initialization failed.

After pressing enter I get a command line. From here I don't know what to do.

I've tried other distros (Lubuntu, Linux Mint), but then even 'nomodeset' didn't make a difference. I have also tried to add 'acpi=off' to the grub line after 'nomodeset', but again only black, even with Ubuntu.

Any suggestion or help will be greatly appreciated!
