This happen on my setup, and it never goes to sleep a.k.a. suspend is off. It only does a screen lock. Thus I believe it is wrong to assign this to the sleep functionality.
I have two screens, one low-res Eizo Nanau corp. FlexScan S2202W 22" 1680×1050 connected over DVI-D and one Samsung Electric Comp. U28E590D 28" 3840×2160 connected over HDMI. The Eizo screen is pretty old, but has better image quality. This machine is a ASUS ROG STRIX B650E-F with an old NVIDIA GeForce GTX 960 graphics card. Both screens are connected to the 960. Its kind of counter intuitive to use such an old graphics card on that motherboard. The Eizo screen is pretty fast while unlocking the machine, the Samsung one is lagging behind. Some apps will then move to the Eizo screen, most notably gnome apps, but not consistently. Doing a test right now the file browser moved, Firefox did, and Warp. Neither Secrets nor Chronium move on this occasion. Repeating this, but without screens turning on, nothing moved. Repeating once more with screens turning off, only the backup app Pica moved. I've been wondering whether this has to do with how many apps that manage to reinitialize before the Samsung monitor turns on, and whether the screens are sequentially initialized or it is done in parallel. Some says it doesn't matter whether the screens are similar, which makes me wonder if they are initialized sequentially. If necessary I can do some further tests. # Systeminformasjon --- ## Rapport - **Dato generert:** 2024-07-14 15:28:58 ## Maskinvare: - **Maskintype:** ASUS ROG STRIX B650E-F GAMING WIFI - **Minne:** 16,0 GiB - **Prosessor:** AMD Ryzen™ 7 7700X × 16 - **Grafikk:** NVIDIA GeForce GTX 960 - **Grafikk 1:** NVIDIA GeForce GTX 960 - **Lagringsplass:** 6,0 TB ## Programvare: - **Fastvareversjon:** 0613 - **Operativsystem:** Ubuntu 24.04 LTS - **Utgave:** (null) - **Type:** 64-bit - **GNOME-versjon:** 46 - **Visningssystem:** X11 - **Kjerne:** Linux 6.8.0-38-generic -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1927948 Title: Windows switch monitor after resuming from sleep To manage notifications about this bug go to: https://bugs.launchpad.net/gnome-shell/+bug/1927948/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
