1.246.  xorg-x11-drv-mga

the driver version written to the Xorg log file in /var/log/ did not reliably match the driver version in use. (The Xorg log file reported version 1.4.1 when the version in use was 1.4.2.) With this update, this error has been corrected and the Xorg log file reports the driver version accurately. (BZ#474209)

some video cards based on the Matrox G200SE chip-set do not have enough installed RAM to support 24-bits per pixel (bpp) at 1024 x 768 pixels resolution. Previously, the xorg-x11-drv-mga driver automatically switched output to 16-bpp when a display being driven by such a card was running at 1024 x 768 (XGA) pixels resolution regardless of the amount of installed RAM. With this update, only cards with 2 MB of RAM or less are automatically switched to 16-bpp. Matrox G200SE-based video cards with more installed RAM can now display 24-bpp at 1024 x 768. (BZ#479919)

the limited bandwidth of the G200SE chip-set caused some 24-bit color modes to be rejected when using the default 32-bpp framebuffer. With this update, a 24-bpp packed framebuffer is now the default for G200SE-based cards. This reduces the bandwidth required and allows otherwise rejected modes to work. Note: the 32-bpp framebuffer is still the default for other chip-sets. (BZ#508039)
