On the same host, this issue does *not* occur with qemuarm-sato-sdk image. 2. On the other host that qemuarm can pop-up the virtual X desktop, the same issue also occurs. So i think this issue is *not* impact by my host. 12270 3 ke.yu 2011-03-03 19:19:32 +0000 After tracking the message between vnc server/client, it is finally root caused as word endian issue. mips linux is bigendian, while x86 linux is little endian, so there should be endian convention between the vnc client/server. the code does have the endian convertion logic and the logic works well in most case. the only issue is that in vncserver mips compiling, there is missing flag "-DLIBVNCSERVER_WORDS_BIGENDIAN", thus the vncserver in mips has wrong endian. Adding the flag can fix this issue. patch is ongoing. 12299 4 ke.yu 2011-03-04 17:00:15 +0000 Fixed by http://git.pokylinux.org/cgit/cgit.cgi/poky/commit/?id=87290a8497e892a65bde4755c4fee8b8ca93424b 12597 5 liangliang.wang 2011-03-14 22:22:51 +0000 This issue does not occur on current nightly build (20110313-2).
