How to fix error with ATI driver "Error of failed request"?
Check if fglrx isn't blacklisted.
To do that you can grep through all of the files in /etc/modprobe.d/:
grep fglrx /etc/modprobe.d/*
In my case this gives following output:
blacklist-local.conf:blacklist fglrx
fglrx.conf:# This file was installed by fglrx
fglrx.conf:alias fglrx fglrx
All I had to do is to edit /etc/modprobe.d/blacklist-local.conf file and comment out line with "blacklist fglrx" by inserting "#" in front of the line. So it looks like this now:
# blacklist fglrx
I hope you could understand what i am writting here and it will help you solve your problem.
there is a nice script smxi for ATI / Nvidia try this:
sudo su
mkdir video
cd video
wget -Nc smxi.org/sgfxi
chmod +x sgfxi
./sgfxi
the script automatically stops X server, detects the video card type, downloads the last video driver from vendor's site, backups xorg.conf and installs the driver
What worked for me:
Use propriety drivers through the "Additional Drivers" application. Going for a manual install of upstream drivers is unnecessary. Open terminal and enter:
sudo aticonfig --initial
and restart your computer. That's it.
That tutorial is simply full of wrong steps and commands and do not describe correctly every passage.

Hey I got the same problem:
X Error of failed request: BadRequest (invalid request code or no such operation)
Major opcode of failed request: 136 (GLX)
Minor opcode of failed request: 19 (X_GLXQueryServerString)
Serial number of failed request: 12
Current serial number in output stream: 12
When I did:
fglrxinfo
It gave me the same output:
X Error of failed request: BadRequest (invalid request code or no such operation)
Major opcode of failed request: 136 (GLX)
Minor opcode of failed request: 19 (X_GLXQueryServerString)
Serial number of failed request: 12
Current serial number in output stream: 12
So I followed the instructions in this link then it worked.
