Hi

   My software version is  flexbuild_lsdk1909_update_311219

   export DISPLAY=:0.0

   apt-get install qtcreator

root@ubuntu-mate:~# qtcreator

Thanks for your reply,

    these kernel modules have been compiled into the kernel by default in flexbuild_lsdk1909_update_311219

    I found these errors occurred in libGAL.so,and galcore.ko is not auto insmod

    When I load the driver, qt still does not work

root@ubuntu-mate:/# lsmod

xt_addrtype 16384 2
xt_conntrack 16384 1

Please refer to the section "Verification in Linux" in "7.2.18 LCD and display transmitter controller" in LSDK 19.09 user guide to do verification step by step.

Please check the console messages after insert display related Kernel modules.

Thanks,

你可以看一下lsdk1909的内核配置文件,你说的这些内核模块默认配置都是Y,并不是编译成模块

如果是内核驱动问题,那么mate桌面应该无法正常显示,现在的问题是qt等一些软件无法运行

我对LSDK1909的软件并未做任何更改,只是apt-get安装qt而已
