-However, if you have problems with auto-detection, you can specify:

- <item>DacSpeed - in MHz
- <item>MemBase - physical address of the linear framebuffer
- <item>IOBase - physical address of the memory mapped IO registers

In order to use most resolutions, it is necessary to install the
'agpgart.o' module. You will probably have to compile the module yourself
(see the notes in the module).

-system memory, and isn't used by the server. The main function of this

<sect>Driver Options

- <item>"NoAccel" - Turn off hardware acceleration
- <item>"SWCursor" - Request a software cursor (hardware is default)
- <item>"Dac6Bit" - Force the use of a 6 Bit Dac (8 Bit is the default)

<sect>Known Limitations
<p>
<itemize>
- <item>No 3D support in this release.
- <item>Running two X servers on different VTs is not supported at this time.
+ <item>Many systems with Intel graphics have issues with setting video modes
+at larger than some small maximum resolution. This is not fixed in the current
+release, but is being actively worked on in the modesetting branch.
+ <item>Bug #5774: Some systems have issues with VT switching. This should
+be fixed with the modesetting brach integration.
+ <item>Bug #5817: Hotkey switching from LVDS to CRT breaks CRT output. This
+is a known issue, but will not be fixed in the current release.
+ <item>Bug #6635: Video is output from an incorrect offset in the framebuffer.
+This is expected to be fixed with the modesetting branch integration.
+ <item>GL_EXT_texture_compression_s3tc is not supported. We can't support the
+extension due to patent restrictions on compression, but may be able to support
+an option for partial extension support in the future. For now, this prevents
+Quake4 and some other games from running.
+ <item>Some X Test Suite cases sometimes fail due to a timeout. These cases
+include: Xt8/XtResizeWindow, Xt8/XtQueryGeometry, Xt9/XtAppAddInput,
+Xt9/XtRemoveInput, Xt9/XtAppAddTimeOut, Xt9/XtRemoveTimeOut, Xt9/XtAddGrab,
+Xt9/XtRemoveGrab.
+ <item>Some X Test Suite cases fail in 64-bit mode: Xlib9/XDrawArc,
+XDrawImageString, XDrawLine, XDrawRectangle, XDrawSegments, XFillArc,
+XFillPolygon, XFillRectangle, XPutImage, Xt11/XtVaGetSubresources,
+XtSetSubvalues, and XtVaSetSubvalues.
+ <item>Some GLEAN test cases fail if DRI is enabled: pointAtten,
+readPixSanity, texCombine, texCube, texEnv, texgen, coloredTexPerf2, and
+coloredLitPerf2.
