SVGALib

SVGAlib is an open-source low-level graphics library which ran on Linux and FreeBSD and allowed programs to change video mode and display full-screen graphics, without the use of a windowing system.^[3][4] Alongside X11 and the General Graphics Interface, it was one of the earliest libraries allowing graphical video games on Linux.

History

The first version of SVGALib was based on version 1.2 of another library, VGALib by Tommy Frandsen.^[5]

Several games like Ambrosia Software's Maelstrom by Sam Lantinga, the first-person game Space Plumber,^[6] and most famously id Software's Doom (alongside an X11 version) and Quake (after the submission of a third-party patch based on leaked source code^[7]) were ported to use SVGALib from other operating systems,^[8] as was Doom porter Dave Taylor's Abuse.

Wolfenstein 3D was also ported following its source code being released in 1995,^[9] as well as the id produced Heretic, Hexen and Hexen II after 1999,^[10] and Descent and Descent II by Parallax Software after 1998.^[11] Certain source ports for Doom, Quake, and Abuse maintained support for SVGALib.^[12] The library is also supported by the MAME/MESS emulator.^[13]

First party Linux games that have supported it include Alizarin Tetris,^[14] Bdash,^[15] Fleuch,^[16] Hatman,^[17] Intelligent FRAC,^[18] Koules,^[19] LinCity,^[20][21] Linberto,^[22] Quadra,^[23] Repton,^[24] SABRE,^[25] Thrust (also supported GGI),^[26] Zarch,^[27] and Zblast,^[28] among others.^[29][30][31]

SVGALib was popular in the mid to late 1990s.^[32][33] A reference book, Linux Graphics Programming with SVGAlib, was authored by Jay Link in 2000.^[34] Around the turn of the millennium, many applications that used it migrated to X11 and SDL,^[35] which could (until SDL 2.0) make use of SVGAlib as a video driver.^[36][37] This was in part due to the risks of privilege escalation due to SVGAlib requiring applications to run from root.^[38][39][40]

As well as not being in keeping with the aesthetic, the LCD also had the annoying habit of showing a warning about being out of range on top of what otherwise looked to be a workable display, especially when playing games that utilized SVGAlib for graphics. I could get around this by launching certain more pliant SVGAlib games such as the final build of LinCity before starting up the offending applications, as for whatever reason this would seem to soothe the nerves of the display, but I was more than happy to leave those headaches behind.

The Quake clients, however, need access to your sound and graphics cards, which requires privileges that normal users don't have. One (bad) way to deal with this is to always run Quake as root. Responsible system administrators will cringe at this filthy suggestion. Making the Quake binaries setuid root is a more acceptable solution. Quake can then be run by regular users and still have the privileges it needs to access the sound and graphics devices. Setuid presents a security risk, though. A clever user could exploit a bug or security hole in Quake to gain root access to your system. Of course, if you don't run a multi-user system, this is may not be a big concern.
