Redshift with Bumblebee? #256
Comments
I have a Lenovo T530 that has an integrated GPU (Intel HD4000) and a dedicated GPU (Nvidia NVS 5400). The screen of the laptop itself and the VGA port on the laptop are connected to the Intel GPU and all other ports (e.g., DVI, DisplayPort) are connected to the Nvidia GPU. |
Hi, just my 2 cents - I had the same issue with my ASUS N56VZ (Intel HD4000) i.e. redshift works on my laptop (xrandr LVDS1) display but not on the external HDMI (connected to the Nvidia Geforce 650M). I managed to make it work by simply running "DISPLAY=:8 redshift". DISPLAY :8 is setup for intel-virtual-output. |
Thanks @birq! That command allows me to run redshift on my external monitor, but it introduces two new problems.
I can tolerate the first issue (don't really use the mouse), but the second is highly annoying. I'll report back if I can discover the cause of this strange behavior. |
This is not perfect either, as redshift-gtk cannot be used then. It would try to attach to a panel on DISPLAY=:8, which of course is only a dummy display server driving outputs. The main panel on the regular :0 DISPLAY would be unused. Ideally, one redshift instance on :0 should be able to handle multiple DISPLAYs, which would solve this problem very nicely. Would adding such an option to e.g. the randr method be worth a consideration, @jonls ? It's already possible to set the screen and multiple crtcs. Thanks! |
I recently installed Bumblebee on Ubuntu 14.04 LTS so that I can connect my second monitor to my laptop by means of an HDMI cable. However, now Redshift no longer dims the external monitor, but only the laptop screen. With Bumblebee disabled and using a VGA cable everything works fine. This seems like the opposite of #23. Is there any way to have Redshift run on both monitors? Thanks!
