> Hello,
> 
> I have the same problem (I think): beamers were working perfectly fine until
> a system update weeks ago.
> 
> My configuration:
> - Fedora 25 beta (but the problem was there with F24 as well)
> - 00:02.0 VGA compatible controller: Intel Corporation Haswell-ULT
> Integrated Graphics Controller (rev 0b)
> - linux 4.8.4-301.fc25.x86_64
> 
> Regular Iijama monitors work fine in VGA (both the one I have at home and
> the one from my office, which is a Prolite XB2485WSU).
> 
> However beamers (rather old, which is typical in universities) do not work
> in VGA: nothing detected with xrandr or anything else. I have this situation
> with two different beamers.

> If I can provide more information, please do not hesitate to ask!
