The norm these days is that a background is sized to each individual monitor. However, this is not how ThinLinc's initial background is set. It completely ignores the monitor information and just stretches the image over the entire framebuffer. This generally looks rather bad, as the proportions are extremely far away from the backgrounds original proportions.
Also note that bug 7218 is probably needed to have access to the correct monitor information.
This should be all done now. Tested server build 3343 on Ubuntu 22.04 and Fedora 38: > MUST: > * The background should fit the largest monitor It does, it also fits all other monitors. > COULD: > * The background should fit all individual monitors regardless of size or position It does, tested with 3 different monitors. I tested different combinations where all 3 had different resolutions, positions, and orientations. > * The background should update when monitor configuration is changed It does, thanks to the fact that we get a Randr event when this happens.
The TAG says: > /sessionstart/background_image > A PNG image used as the initial background. The image will always be scaled to cover the entire screen. This should be updated now that the image fits each monitor.
The TAG and sessionstart.hconf have been updated now: https://www.cendio.com/resources/docs/tag-devel/html/config_sessionstart.html?highlight=background#server-config-sessionstart-background_color
Created attachment 1149 [details] The background overlaps to the next monitor Easy to miss depending on the order of the monitors. In this example, I shifted one monitor vertically. The left background overlaps the right.
Created attachment 1150 [details] The Thinlinc logo is too far to the right Also now when the monitor size is too narrow for the background, the Thinlinc logo looks displaced. It should be more to the left, I think.
The overlap issue, and centering of the background image, have now been fixed.
Tested again and it looks better with the centering. Tested with two monitors, no overlap.
