can't detect HDMI - ATI Mobility Radeon detected as Network Controller

Sometimes, the HDMI port isn't detected when I do a xrandr, I can only see VGA in it.

lspci tells me that ATI Mobility Radeon HD 4300 Series is detected as a network controller which seems to me to be the issue.

I can't reproduce this problem at will, since sometimes it does detect the HDMI port and sometimes it doesn't.

Here's the output of `lspci` when I do detect the HDMI connected monitor:

Please let me know how I can fix this i.e. make arch always detect my HDMI port.

Thanks.

Re: can't detect HDMI - ATI Mobility Radeon detected as Network Controller

First of all, WTF how? Sounds like a firmware bug, check whether there's an update available, though this reads quite weird in any case. Do you share a Windows install by chance? Make sure fast boot is disabled.

Re: can't detect HDMI - ATI Mobility Radeon detected as Network Controller

There are no firmware updates available.

The laptop I'm using did have windows installed earlier.. but there's only Arch now.

So, sometimes I restart my laptop and everything seems fine again. Is there maybe a way to somehow restart it without restarting it? (i.e. only reload the drivers and find the HDMI port)
