How To Fix Error: "Check your video drivers. Your system is currently running without video hardware acceleration."

de flag

I am running Ubuntu 20.04 Server (Intel Pentium G3240, XEON E3-1200 integrated GPU) with Cinnamon desktop (ver. 4.4.8). When I login I get the message above in a popup window. The system is running okay, but CPU is pretty high. I have been searching for hours and couldn't find a solution. I did run vainfo:

    vainfo
    error: XDG_RUNTIME_DIR not set in the environment.
    libva info: VA-API version 1.13.0
    libva error: vaGetDriverNameByIndex() failed with unknown libva error, driver_name = (null)
    vaInitialize failed with error code -1 (unknown libva error),exit

I searched for how to set the XDG_RUNTIME_DIR but that was over my head.

Does your machine meet the minimum video requirements for the cinnamon desktop? Your issues seems to be me expected given your description (Cinnamon isn't a *light* desktop thus it's higher requirements when contrasted to others; why it recommends hardware acceleration)

It's an Intel XEON E3-1200

That's a CPU & not real GPU. Cinnamon expects a 3D accelerated graphics card with 256MB minimum RAM (GPU RAM unshared) ; if you don't have that; you're forcing the CPU to perform the function of graphics normally done by the GPU (your CPU doesn't have 'hardware acceleration'; it's performed by the CPU itself so you'll see higher CPU workload). You can wait for others to comment; I haven't monitored cinnamon updates/changes for some time so my knowledge will be dated.. Cinnamon seems a strange choice for a server to me; too heavy.

Welcome to AskUbuntu, the XEON E3-1200 doesn't have an integrated GPU, you have to specify the exact CPU model, `lscpu`. If the model name ends with a `0`, it doesn't have a GPU. You need to add a card or change a CPU.

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
