relied on the generic VGA layer to restore text console fonts for us when shutting down the server or VT switching back to the text console. This has worked rather well but it has some downsides on Linux: a. Many people use fbdev as console text mode. In this case it is not necessary to save/restore console fonts as the console is running in graphics mode anyway. b. Some architectures don't have a fbdev console but require a full POST of even the primary card (ie. IA64). This posting has to take place before we even have a chance to save anything. Therefore the fonts we save are the once written to the chip by POST, not what has been programmed by the user. c. Certain chipsets utilize the BIOS to perform mode setting. This may interfer with the vga save/restore font function in a strange way. It would therefore be preferrable to let the OS - which has been used to set up the font in the first place - take care of saving/restoring the data. I will attach a patch which will do so for Linux. To make this fully functional a small patch needs to be applied to the Linux kernel. To disable this feature add: #define DoOSFontRestore NO to your host.def. (Bugzilla #2277) |
