-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA512 Ahoi, I use Arch on a Thinkpad T480 with the Lenovo Thunderbold 3 dock. I've attached 2 1440p monitors to it and I was using them for a while now. For a few days or so I can't get them to work anymore. Usually I disable my Notebooks internal screen and enable the 2 1440p displays like this: ``` xrandr --output DP1-1 --mode 2560x1440 --refresh 144 xrandr --output eDP --off xrandr --output DP1-2 --mode 2560x1440 --refresh 144 --right-of DP1-1 ``` This used to work quite nicely. No idea if the refresh rate actually worked. I have no way to test that but the resolution sure did. Now when I do this I get this error: ``` xrandr: Configure crtc 0 failed ``` I can only drive both displays at 1920x1080. When I increase the resolution to 2560x1440 I get this error and the higher resolution can't be set. I don't know why this doesn't work anymore. Could it be a driver issue? I've got a nvidia GPU with the proprietary driver and the integrated intel with the open source driver and it wouldn't be the first time intel or nvidia fucked their drivers up. - -- Greetings Ricardo Band https:// www.ricardo.band mailto:// email@ricardo.band xmpp://jabber@ricardo.band -----BEGIN PGP SIGNATURE----- iQIyBAEBCgAdFiEEhyzgFNiV8yZuI1T5Gp1lfQa1gg4FAl189YYACgkQGp1lfQa1 gg6BaQ/2MbyhaCtK5uP7GC1Zads8KZ93pXSzrm5udreO/+z2ODW7jQe6Fy+0sSNY rkT8rcvQkylNwPyXyol3CbjXNDzxN17E2u9dJrrScIuXs/LcnfxtIAvlPToKsui1 H4JJbJKnLjZaUs0shrll82PJA4PXSe3t/t0hzflGK+Np+G1rm6Nc8y3Ev+cYkBt4 clW1sjEidHJN7lIfVsOcN72oeIhPJ0hO1JSV8E3lkLZ+78LYMKTf5ZKXO1E/2S5D fd2GOXYuvEJUZ9HBl0yqQTy0B/VGO7w0ui5z0DpvwtBLY9leAbD2pTmzAi3UkZeD MIcO7ZImt9N7rufgEkuUaM1/Qx6YZTh16+dWcKbFMUjASuCbz35Z5yvIprO7h/sW 8dRB4aCuq3M37Z4X8R1w65jkHV8EfrLuhyOFRZ/2FKGBzmwDa4V4fFbMH3fAtahJ uPjdszWVblzFRCnFTvwWXIRAK1dAEIgWMRbSoBMDcnuQxcG1LNaB9QnG5J0YkJAJ os+04Tsf6nRcA+/58SJdpd7BfTarQNEFsAY+5VHxGHgFJh1MnzXXbuVs13JlzYkI QmHTCa3OJ2TexlJzhBDyye7zGKbD4PxxKFiu3DKcUs+R3Ye30SdMzEki7s3VXejB vIbPfrqftWJwmUJIqyzgNFdf0/IfC465ikWtaUMxC4NeqZK+Pg== =xHOd -----END PGP SIGNATURE-----
