I switched from Windows to Xubuntu 18.04 LTS a couple of weeks ago.
If I connect my laptop to HDMI the download rate sinks to zero and my Internet connection vanishes. The second I disconnect the HDMI cable the connection re-establishes and everything works as usual.
I have an Acer Travelmate 5742, an Intel(R) Core(TM) i5 CPU M 560, and my wireless interface is:
description: Wireless interface product: BCM43225 802.11b/g/n vendor: Broadcom Inc. and subsidiaries
I have a proprietary driver for my WiFi. Furthermore, I had to make some adjustments to be able to use brightness control:
Section "Device" Identifier "card0" Driver "intel" Option "Backlight" "intel_backlight" Option "TearFree" "true" BusID "PCI:0:2:0" EndSection
Can anything of my adjustments cause these problems?? I switched to VGA (which works perfectly) but I do not intend to stay this way…
I appreciate any help! Thank you!
