Since doing that, I can't log in. While booting, everything proceeds as usual, with normal output, until the SLiM login screen is supposed to appear. But instead of the SLiM login screen, I get a blank screen with a small white cursor in the upper left, and I can't log in. Has anyone seen anything like this in the past? Here are some observations I've made about the situation: * GuixSD shuts down normally if I issue the "shutdown signal" from VirtualBox. This indicates the OS is actually still running. * I waited over 8 hours, and the login screen did not appear. * I tried blind-typing my user name and password, but the blank screen remained. * When I boot from the previous system generation, there is no problem. * When I replace SLiM with SDDM in my OS configuration and reconfigure, the same problem occurs. * However, one time only, while trying to boot using SDDM instead of SLiM, I got to the SDDM login screen. But when I typed in my username and password and hit enter, I received the same blank screen as before and ultimately could not log in. Every other time I've booted the VM, I didn't even get to the SDDM login screen, so I don't know why I was able to reach the login screen that one time. * I tried pressing control+alt+F2 etc. to switch to different virtual tty, but it didn't work. The blank screen remained. * I examined various system logs, but I could not find anything that jumped out at me as causing the problem. It's entirely possible I missed something important, though; I just checked a few places. There is more that I could try - for example, I could try starting an ssh server in my VM and logging in that way. I could also try drilling deeper into the X server logs, since that seems like the obvious next step, since the problem occurs for both SDDM and SLiM. I could also try reinstalling GuixSD in a new VM. But I haven't tried any of this yet due to lack of time. If anyone has any advice or has seen this before, please let me know. Thank you! =2D-=20 Chris --=-=-= Content-Type: application/pgp-signature; name="signature.asc" -----BEGIN PGP SIGNATURE----- iQIzBAEBCAAdFiEEy/WXVcvn5+/vGD+x3UCaFdgiRp0FAlvLgE8ACgkQ3UCaFdgi Rp3GOA/+Me8YRsysLxLsvzN6ZTKyGOSZFAmfx4jwZxaYH499McM7p0Q+jtcbN8Je fhsWiEdC35Ub8yyZZLPh04eNIWcE6jR032P9TkAxxRJS2HVnW0Ux2WdrTA6GHuVD edEbL5dKA3SjelaIS1VW1c2WOAr+cmYMfJ2acEswrZTv6ejjaqNyRwqVMj1hJUVv NsN/0CQrJyscLLiZlUsUqJQSSE9EPCc/bHnZ/WAFkoYBtHkb3VECeEbkLd3EzurD aLcyFZ68vd8rAtKy4mk3EvJ2PgHaQo+WA04rA6OJs7NEVc/40r+EQ5TrrsRawp+s iWoL8OGfeUYoQ0MVeAaIkaMwMMl8WvkR67pAsBRQ6DsWfh6ojJzhjcJ7kBZSal7Y aAoPeh5/5S9MzoYs6UFZPaRY5t6iQHa5L88nOfa3xnjmFdExnS0D1qMpaklrdsos x4QsHZI8lldOqpNrbeO81Fvs5RNEY9pPQOuo9h5Jec5h9dbiNedCkHMq6JZy3jpQ +QxDeR6OluRfMUdDGe4kcB8npyFe2ce2bNUAt+qhUsDE9G9iVTAy8sqLmLShQE4z 4fkxLynvqK8jRX7ymH7rWvjm0OuaKyCegmp2mKAIHMH6n70htM7ps3kbCXxC5TUN IIM+BcZP/CLSqfA6GrwGrZL/ov34a5/XvM7+hksWdMRv/ldVFBo= =wWOg -----END PGP SIGNATURE----- --=-=-=--
