Choppy juddery video Zorin 7.1

Does not seem to offer the last step.....Addit ional Drivers !!

So how did you get to “Additional Drivers” as shown by your screenshot ?

I used this code from Mark Greaves


Can you try the fglrx-updates driver.

I’d be amazed if the proprietary drivers from AMD were worse than the open source ones :o

After installing fglrx and rebooting … is there a Catalyst Control Panel in the menu’s somewhere ?

and can you post the output from:

sudo lshw -C display

again, so we can be sure fglrx loaded

can you also post the output from:

ls -a /etc/X11

Can you clarify what version of Zorin you’re running and if your system is 32 or 64 bit ?


Latest Zorin 7.1 64 bit.

Just been told I am going shopping !!! Sorry for delay. Will be 1-2 hours. Be back then.


Okey dokey :slight_smile:

No catalyst panel as I can see.


next one…

Now have “AMD unsupported hardware” in bottom right corner

Have found Catalyst Control Center.

Can you run:
sudo updatedb
then post the output from

locate xorg.conf

as catalyst doesn’t apper to have created one.

Hi ,

Spent all morning playing same (freshly recorded) clip on Zorin. Whether I select VLC Sm player, or Videos, the play back is not smooth. Certainly not unwatchable, but not smooth. On playing same clip in Win 7 laptop (i3 and 6gb) using VLC, Media player and Media player classic the results are smooth as silk.

Now, I really want to use a Linux base as, short of the video editing, I have found all I want to do from a second computer.

This is new build with AMD A10k proc with inbuilt HD radeon grahics and 8gb fast 2100 ram so I’m not thinking it’s the processing power of machine !

Prior to install of Zorin, Camtasia ran fine on the machine with Win 8 trial and all playback using above progs. was smooth.

Can I install another Linux to run alongside Zorin like Windows dual boot ?

Thanks for your input.

Seems to me this is JUST a driver issue … you STILL don’t have an xorg.conf file in the right location.

is there an option in the catalyst control center to create one … or “save settings” or similar ?

if not, we’ll try manually creating one.

I certainly cant see an option. Please find screenshot

OK, what happens if you run:

sudo aticonfig --initial -f

then what’s the output from

ls -al /etc/X11/xorg.conf

I’m going to post a link here that it may be a good idea to reed before you reboot … specially the bit on what to do if you get a black screen after rebooting

OK, what happens if you run:
Code: [Select]
sudo aticonfig --initial -f

No support adapters detected

then what’s the output from
Code: [Select]
ls -al /etc/X11/xorg.conf

OK, let’s try this a different way

See here:

do you think you could do that, or do you require help ?

if you need assistance, please post the output from:

uname -a

so we can see if you’re running 32 or 64bit
