content: Products like Delock95253are very very expensiveQuoteEUR 240and it's not clear how good is the Linux support. Delock doesn't mention Linux in the list of supported OS, and Linux has the SM750 code (drivers/staging/sm750fb/sm750.c) in the staging drivers sectionCode:------------------------------------------------------------------------------------------------------bool "Staging drivers"---help---This option allows you to select a number of drivers that arenot of the "normal" kernel quality level. These drivers areplaced here in order to get a wider audience to make use ofthem. Please note that these drivers are under heavydevelopment, may or may not work, and may contain userspaceinterfaces that most likely will be changed in the nearfuture.Using any of these drivers will taint your kernel which mightaffect support options from both the community, and variouscommercial support organizations.If you wish to work on these drivers, to help improve them, orto report problems you have with them, please see thedrivers/staging/<driver_name>/TODO file to see what needs to beworked on, and who to contact.Experience with Silicon Motion? Cheaper miniPCIe video devices?

content: There are adapters to convert mini PCIe to full size PCIe, then just use whatever cheapest GPU you can find.

content: Quote from: NiHaoMike on September 25, 2021, 08:20:04 pmwell, yes, but I have a small computer with a mini PCIe, and there is not so much space for a big GPU; also big GPUs consume a lot of electricity and this is constraint for me.Any recommended "mini PCIe to full size PCIe" adapter? Brand? Model?

content: If space/power are a constraint, would a USB display adapter work instead?Supposedly, DisplayLink devices have some Linux support and are way cheaper than €240...You will probably lose 3D/2D acceleration as it's not a full GPU, so it may not work for you.
