<div>Hi everyone!</div>
<div>I have a laptop with a dual boot - Win 7 and Xubuntu 13.10.</div>
<div>The laptop is an Acer Aspire 4810TZG and it has a dual
graphic card, Intel + ATI Mobile Radeon HD4330.</div>
<div>
Unfortunately, during my neverending quest for the perfect
Linux system, I have tried to use a program to update my ATI
drivers from:</div>
<div><a moz-do-not-send="true"
href="http://www.thefanclub.co.za/how-to/ubuntu-amd-catalyst-install">http://www.thefanclub.co.za/how-to/ubuntu-amd-catalyst-install</a></div>
<div><br>
</div>
<div>Needless to say, after following the procedure and the
installation of those drivers, when I log into Xubuntu, my
screen has blue and black stripes.</div>
<div><br>
</div>
<div>Short of backing up everything and re-installing Xubuntu,
does anyone know how I could remove those drivers and install
working drivers?</div>
<div>Note that using the Ubuntu recovery option I can use a
command line (even if when I tried it seemed not working as
expected) - or I can use SystemRescueCD.</div>
<div><br>
</div>
<div>Thanks!</div>

<p>from command line have you tried dpkg with the purge option<br>
dpkg --purge [package name]<br>
</p>
<p>even if you boot to your blue striped screen you should still be
able to ctrl+alt+F[1-5] for a terminal login...<br>
</p>
<p>hope it helps, good luck. Find out where the package broke and
give some feed back to it's author. It looks pretty good.<br>

<p>p.s. I had something similar happen a ways back and it turned out
to be a frequency setting that was the culprit.<br>
