Hi,

I'm sorry for the breakage, but unfortunately the report arrived just a
couple hours too late and the broken version migrated to testing before
it could be blocked.

As others have mentioned, unfortunately 304.132 seems badly broken. See
https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=840342

Being a closed source proprietary driver, we as maintainers cannot do
anything and we have to wait for Nvidia to fix it.

Unfortunately the 304xx series is quite old and neither me nor the other
Nvidia maintainers have hardware that is supported by it, so we
physically cannot run it.
So when a new release is out the only thing we can test is that the
kernel modules build, and nothing else. Given we don't have HW and it's
closed source, we have to trust that Nvidia tests it properly, and
upload in good faith.

The only workaround is to downgrade and pin to the version in
jessie-backports.

There is a thread on Nvidia's forum, I already chipped in but there have
been no comments from Nvidia:
https://devtalk.nvidia.com/default/topic/968892/geforce-7300le-with-304-132-glxinfo-fails-now-with-quot-x-error-of-failed-request-badvalue-quot-

I encourage everyone who is affected by this bug to post on that thread,
to try and draw attention to it, so that we can get a fix.

Meanwhile, for your KDE bug report, please feel free to merge it into
the bug report mentioned above.

Kind regards,
Luca Boccassi
