didier gaumet composed on 2021-05-10 09:13 (UTC+0200):DRI not working in Debian while working in Opensuse: I would surmise that is a missing firmware in the former and not in the latterii firmware-linux-free 20200122-1 all Binary firmware for various drivers in the Linux kernel ii firmware-misc-nonfree 20210315-2 all Binary firmware for various drivers in the Linux kernel ii intel-microcode 3.20210216.1 i386 Processor microcode firmware for Intel CPUs What other firmware could an ancient Intel GPU need?
Sorry for the wrong suggestion: all troubles I have had in the past with DRI not showing with Intel cards were firmware related
To be certain, search for the firmware word in the system logs.But I think that firmware-misc-nonfree is the needed firmware for Intel graphic cards and you have already installed it
Alexander V. Makartsev have good suggestions in his reply. If it does not work (but I don't think so) you could have to manually specify a DRI section in a Xorg configuration. I have forgotten how to do it but it is probably indicated here:
