TigerVNC provides the levels of performance necessary to run 3D and video applications; it attempts to maintain a common look and feel and re-use components, where possible, across the various platforms that it supports. TigerVNC also provides extensions for advanced authentication methods and TLS encryption. %package -n xorg-x11-Xvnc Requires: xinetd Requires: xkeyboard-config Summary: TigerVNC implementation of Xvnc Group: System/X11/Servers/XF86_4 %description -n xorg-x11-Xvnc This is the TigerVNC implementation of Xvnc. %prep %setup -T -b1 -b2 cp -r ../xorg-server-*/* unix/xserver/ if [ -e unix/xserver/hw/xfree86/modes/xf86gtf.c -o -e unix/xserver/hw/xfree86/utils/gtf/gtf.c ];

In most cases this effectively prevents the core protocol bell from ringing: if no BellProc() is set for the device, no attempt is made to ring a bell. This patch ensures that an XKB bell event is sent also when the core protocol bell is rung end thus an appropriate action can be taken by a client.

This commit includes the creation of a new REQUEST_AT_LEAST_EXTRA_SIZE macro in include/dix.h for the common case of needing to ensure a request is large enough to include both the request itself and a minimum amount of extra data following the request header.

From fe5018e0564118a7a8198fa286186fdb9ed818c7 Mon Sep 17 00:00:00 2001 From: Takashi Iwai Date: Tue, 19 Aug 2014 15:57:22 -0500 Subject: [PATCH] fb: Fix invalid bpp for 24bit depth window

We have a hack in fb layer for a 24bpp screen to use 32bpp images, and fbCreateWindow() replaces its drawable.bitsPerPixel field appropriately. But, the problem is that it always replaces when 32bpp is passed. If the depth is 32, this results in bpp < depth, which is actually invalid. Meanwhile, fbCreatePixmap() has a more check and it creates with 24bpp only when the passed depth <= 24 for avoiding such a problem. This oneliner patch just adds the similar check in fbCreateWindow(). This (hopefully) fixes the long-standing broken graphics mess of cirrus KMS with 24bpp. Signed-off-by: Takashi Iwai Reviewed-by: Keith Packard --- fb/fbwindow.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/fb/fbwindow.c b/fb/fbwindow.c index 368c4b883b31..c90175faa078 100644 --- a/fb/fbwindow.c +++ b/fb/fbwindow.c @@ -33,7 +33,7 @@ fbCreateWindow(WindowPtr pWin) { dixSetPrivate(&pWin->devPrivates, fbGetWinPrivateKey(pWin), fbGetScreenPixmap(pWin->drawable.pScreen)); - if (pWin->drawable.bitsPerPixel == 32) + if (pWin->drawable.bitsPerPixel == 32 && pWin->drawable.depth <= 24) pWin->drawable.bitsPerPixel = fbGetScreenPrivate(pWin->drawable.pScreen)->win32bpp; return TRUE; -- 2.0.4 ++++++ U_fb_Fix_Bresenham_algorithms_for_commonly_used_small_segments.patch ++++++ Subject: fb: Fix Bresenham algorithms for commonly used small segments.

Said patch does indeed remove the problematic writes to bad memory, however it also introduces errors in the algoritm. This patch has the effect of reverting said patch and adding an if in the proper location to catch the out of bounds memory write without causing problems to the overall algorithm.

Reason: for link local addresses the XDMCP server would need to either know the interface thru a scope identifier or try all available interfaces. If they don't this address will fail in which case the XDMCP server could still try the other addresses passed - however some only try the first address and then give up. Even if this seems to be the wrong place to fix this it seems to be easier than fixing all display servers.
