That is useless, since the reported symptomes do not apply to non-working H= aswell. Since the last update of the OS - today, CURRENT 277900, the high res conso= le is gone and has fallen back to the 800x600 pixel. The same with the X11 server's displa= y resolution. I can not use VESA driver on the Lenovo ThinkPad E540 with i5-4200M, since = it doesn't startup. I have to use xf86-video-scfb which is a pain in the ass. An alternative is to use Ubuntu on the Lenovo E540 and L540 we purchased. --Sig_/Sa9QnHNF78rU2y_dEhbf4e3 Content-Type: application/pgp-signature Content-Description: OpenPGP digital signature -----BEGIN PGP SIGNATURE----- Version: GnuPG v2 iQEcBAEBCAAGBQJUyrqNAAoJEOgBcD7A/5N8SF0H/A0g+N7jyUay88JHb+AntT2Z bGyHM5xCiDdbEnbXkF1vzG1JdrAsfVtsG6ri7JqU2jFB2LTNwxQy2JT0iWQAwLiz zex5s1FVSaKfuSUtZB2nf3A8wyE/nfrXLUMvCTsa/pJO1g3SAsbeA+1ZK2WOAYA0 FtCtDzEb0dgOaZ+be9OEFTnu61/gNkWO+0HDTM0XU8r27xbJwbbfsISdnIoYxC6i 332JdCwXj4E9rpPB6YzBjq1vn9c7tmVyYLVf1xO+Jp++bh61VFclciig6+emeP4b mKVeRmmhAXMGMNge4LqUi6/4GcfC/vTtwWbJCJJxRLSuL/XB2ULKRubAh02/X30= =rGst -----END PGP SIGNATURE----- --Sig_/Sa9QnHNF78rU2y_dEhbf4e3--
