(F00:80x25=VGA, F01:80x50=VGA, F02:80x43=VGA, F03:80x28=VGA, F05:80x30=VGA, F07:80x60=VGA, 309:132x25=VESA, 30A:132x43=VESA, 30B:132x50=VESA, 30C:132x60=VESA, (8)120:132x25=BIOS, (8)121:132x43=BIOS, (8)122:132x50=BIOS, (8)123:132x60=BIOS) Pre-KMS it used to be that common vga= modes were useless, so I took to using 0x121 to escape from 80x25 screens. Using 0x8121 required specifying an appropriate font via config file. Even after KMS began, vga=0x8121 continued to work, and still does at least through kernel 3.4.47. Now with kernel 3.11.x (openSUSE 13.1) and 3.12.rc6 (Mageia 4): boot: ttys OK, whatever font, rows and columns kernel determines unless specified otherwise on cmdline via vga=. video= and resolution= on cmdline have no effect. Vga= still works too if font is correctly specified by config file, but only for 0x12# BIOS modes. After startx is started, before being stopped, ttys remain functional. Once startx is stopped, ttys may or may not remain functional. Sometimes after startx has been run exactly once since booting they continue to be useful. Other times, the rows and columns are no longer remembered, switching to fonts appropriate to an 80x25 screen, but outputting more than 80 columns and 25 rows, scrambling the output in part via line breaks absent when needed at column 80. -- "The wise are known for their understanding, and pleasant words are persuasive."
