Re: Deactivating and Reactivating the display of a NUC 13
Sorry, forgot to mention that: It did move with the USB-C-Cable. It's a standard Amazon Basic 0,9m USB-C-to-DP-Cable, bought quite recently. Am Do., 6.

Re: Deactivating and Reactivating the display of a NUC 13
Hello, I have exchanged the connections - one NUC from HDMI to USB-C and the other from USB-C to HDMI. The problem persists. I have not yet bought a new USB-C-to-DP-Cable and, unfortunately, don't have another one at hand - only tons of DP and HDMI-Cables. I have bought an active HDMI-2.1-to-DP1.4-Connector, but only got a display output of it intermittently. I strongly suspect that the problem is my monitor. At the moment I am unwilling to buy a new one, since it supports 4k at 120hz and has four display connectors. Buying a new monitor with these features would cost me most likely more than 1k. My current one was a bargain at 800 Euros. Yours sincerely Stefan Am Mo., 3.

Same laptop worked without issue with a Lenovo monitor and same cable so I'm blaming the Samsung. It seems from some other issues the USB-C support was tacked on, not well integrated. Although things have gotten better recently, I just don't know why. Possibly some update to the Lenovo laptop has helped.

Sorry maybe I have missed the information but ... Have you tried the USB-DP cable on the other NUC? And/or moved the DP end to the other connector? Does the problem move with the cable or stay with the original NUC? Do you have another USB-DP cable and have you tried that? > Your sincerely > Stefan

Hello Timothy >Do both NUC's have the same behavior or is just one of them having this >problem? If just one of >them is having this behavior is it the DP or HDMI? I have just done some tests and it's only the USB-C-to-DP NUC that is problematic. The HDMI one goes into suspend and wakes up without any problems. Unfortunately my monitor only does 120hz on the Display Port Connectors and I am by now very much used to the much smoother motion of 120 hz vs 60 hz. I am, according to lsmod, using the i915 driver. At the moment I am considering contacting the maintainer of the driver - maybe he/she can help with this. Your sincerely Stefan

Deactivating and Reactivating the display of a NUC 13
Hello everybody, This is a revised translation of a posting to the German Debian mailing list. Unfortunately nobody there was able to help me with my problem but I hope that on this list with a much wider list of readers somebody might have encountered my problem and found a solution for it. I have two NUC 13, one for work and one for private use. Both are running Debian 12 Bookworm with Gnome 43 and Wayland/Weston. My monitor is a Acer Predator XB273KGP, which has four connectors, two Displayport 1.4 and two HDMI 2.0. The Display port can do 120hz when connected via DP. One of the NUCs is connected with an USB-C-to-DP-Cable and the other one via HDMI 2.0 with only 60 hz. The other ports are used by other computers. My problem is that once the monitor is deactivated – either by manually switching it off or by DPMS - the only way to get a picture again is either to reboot the NUC or detach and re-attach the USB cable. The monitor simply complains that there is "No Signal" This runs counter to my intended usage. I want to enable power saving during the day and reactivate the NUC with a keypress when I want to check my emails or search Google. Also, the NUC is connected to my video projector via HDMI and I want to turn the computer display off when watching movies on the big screen. An active computer is both an unwelcome distraction and a waste of energy. Do you have any suggestions on how to fix this issue? I suspect that this is not the fault of my monitor – I have a windows pc for gaming and it awakes from suspend with a keypress without any problems. It is connected to another DP Port via a high quality DP cable. I do not even have a workaround until a long-term solution is found. At the moment I completely shutdown the NUC after use and start it when I want to use it. Luckily this takes only a few seconds – my NUCs are fast, especially with a Samsung 990 Pro – but I am still looking for a better way to handle this. Yours sincerely Stefan
