Hi debian users. I use Debian Etch and the i810 driver for my Intel 945GM integrated graphics card. My laptop is a Fujitsu-Siemens Amilo Li 1818. When I first started using Debian I had the problem that X would not start, because there weren't any usable modes. I installed 915resolution, which fixed this problem and let me start X in the 1440x900 widescreen mode which is pretty optimal for most uses.
However, sometimes I might want to play a game at a lower fullscreen resolution. Let's say I want to play Pingus at 800x600 fullscreen. I run [EMAIL PROTECTED] $ pingus -g 800x600 -f The game starts up as a borderless window in the middle of the screen. That is, fullscreen doesn't work. The same thing happens with any other programs that try to use any fullscreen mode other than 1440x900. This is pretty deadly to most fullscreen games that set lower resolutions for speed. The first place I looked was in xorg.conf. Sure enough, I have the right modes defined: Code: Section "Screen" Identifier "Default Screen" Device "Intel Corporation Mobile 945GM/GMS/940GML Express Integrated Graphics Controller" Monitor "Generic Monitor" DefaultDepth 16 SubSection "Display" Depth 8 Modes "640x480" "800x600" "1024x768" "1280x1024" "1600x1200" "1440x900" EndSubSection SubSection "Display" Depth 16 Modes "640x480" "800x600" "1024x768" "1280x1024" "1600x1200" "1440x900" EndSubSection SubSection "Display" Depth 32 Modes "640x480" "800x600" "1024x768" "1280x1024" "1600x1200" "1440x900" EndSubSection EndSection I use 16bpp since 32-bit modes are not properly supported by i810. There is a reference for this, but you'll have to take my word for the moment. These modes were obtained by querying my card with 915resolution: [EMAIL PROTECTED] # 915resolution -l Intel 800/900 Series VBIOS Hack : version 0.5.2 Chipset: 945GM BIOS: TYPE 1 Mode Table Offset: $C0000 + $269 Mode Table Entries: 36 Mode 30 : 640x480, 8 bits/pixel Mode 32 : 800x600, 8 bits/pixel Mode 34 : 1024x768, 8 bits/pixel Mode 38 : 1280x1024, 8 bits/pixel Mode 3a : 1600x1200, 8 bits/pixel Mode 3c : 1440x900, 8 bits/pixel Mode 41 : 640x480, 16 bits/pixel Mode 43 : 800x600, 16 bits/pixel Mode 45 : 1024x768, 16 bits/pixel Mode 49 : 1280x1024, 16 bits/pixel Mode 4b : 1600x1200, 16 bits/pixel Mode 4d : 1440x900, 16 bits/pixel Mode 50 : 640x480, 32 bits/pixel Mode 52 : 800x600, 32 bits/pixel Mode 54 : 1024x768, 32 bits/pixel Mode 58 : 1280x1024, 32 bits/pixel Mode 5a : 1600x1200, 32 bits/pixel Mode 5c : 1440x900, 32 bits/pixel Why isn't X taking the extra modes? I consulted /var/log/Xorg.0.log. It's difficult to see which parts are relevant, so the full log is available on request (unfortunately, I do not have webspace available at present, and attaching it to the message seems to cause it to be blocked). Anyway, I excerpt a bit below: [massive list of mode details, some with sensible attributes, some all zeroes: see below for example] (WW) I810(0): config file hsync range 51.4286-56.8421kHz not within DDC hsync ranges. (II) I810(0): Generic Monitor: Using hsync range of 51.43-56.84 kHz (II) I810(0): Generic Monitor: Using vrefresh value of 60.00 Hz (II) I810(0): Not using mode "640x480" (no mode of this name) (II) I810(0): Not using mode "800x600" (no mode of this name) (II) I810(0): Not using mode "1024x768" (no mode of this name) (II) I810(0): Not using mode "1280x1024" (no mode of this name) (II) I810(0): Not using mode "1600x1200" (no mode of this name) (II) I810(0): Increasing the scanline pitch to allow tiling mode (1440 -> 2048). (--) I810(0): Virtual size is 1440x900 (pitch 2048) (**) I810(0): *Built-in mode "1440x900" (++) I810(0): DPI set to (96, 96) Please note the "Not using mode" message. Yet the 1440x900 mode is being found fine, I guess because it's a 'build-in mode'. Here's an example of what looks like a valid mode in the mode details list: *Mode: 41 (640x480) ModeAttributes: 0x9b WinAAttributes: 0x7 WinBAttributes: 0x0 WinGranularity: 64 WinSize: 64 WinASegment: 0xa000 WinBSegment: 0x0 WinFuncPtr: 0xc00077f3 BytesPerScanline: 1280 XResolution: 640 YResolution: 480 XCharSize: 8 YCharSize: 16 NumberOfPlanes: 1 BitsPerPixel: 16 NumberOfBanks: 1 MemoryModel: 6 BankSize: 0 NumberOfImages: 18 RedMaskSize: 5 RedFieldPosition: 11 GreenMaskSize: 6 GreenFieldPosition: 5 BlueMaskSize: 5 BlueFieldPosition: 0 RsvdMaskSize: 0 RsvdFieldPosition: 0 DirectColorModeInfo: 0 PhysBasePtr: 0xc0000000 LinBytesPerScanLine: 1280 BnkNumberOfImagePages: 18 LinNumberOfImagePages: 18 LinRedMaskSize: 5 LinRedFieldPosition: 11 LinGreenMaskSize: 6 LinGreenFieldPosition: 5 LinBlueMaskSize: 5 LinBlueFieldPosition: 0 LinRsvdMaskSize: 0 LinRsvdFieldPosition: 0 MaxPixelClock: 230000000 And here's one that looks invalid: Mode: 38 (0x0) ModeAttributes: 0x0 WinAAttributes: 0x0 WinBAttributes: 0x0 WinGranularity: 0 WinSize: 0 WinASegment: 0x0 WinBSegment: 0x0 WinFuncPtr: 0x0 BytesPerScanline: 0 XResolution: 0 YResolution: 0 XCharSize: 0 YCharSize: 0 NumberOfPlanes: 0 BitsPerPixel: 0 NumberOfBanks: 0 MemoryModel: 0 BankSize: 0 NumberOfImages: 0 RedMaskSize: 0 RedFieldPosition: 0 GreenMaskSize: 0 GreenFieldPosition: 0 BlueMaskSize: 0 BlueFieldPosition: 0 RsvdMaskSize: 0 RsvdFieldPosition: 0 DirectColorModeInfo: 0 PhysBasePtr: 0x0 LinBytesPerScanLine: 0 BnkNumberOfImagePages: 0 LinNumberOfImagePages: 0 LinRedMaskSize: 0 LinRedFieldPosition: 0 LinGreenMaskSize: 0 LinGreenFieldPosition: 0 LinBlueMaskSize: 0 LinBlueFieldPosition: 0 LinRsvdMaskSize: 0 LinRsvdFieldPosition: 0 MaxPixelClock: 0 Any ideas? Google has left me cold, as has the debian forum. It may seem a minor issue but it stops me doing a lot of things.
