LS1028A Ubuntu-Mate QT

lizuobin — Mon, 27 Apr 2020 03:28:17 GMT

I use the ubuntu mate system on the ls1028a-rdb platform and try to run some qt test programs, including qtcreator, but it fails

My software version is flexbuild_lsdk1909_update_311219

export DISPLAY=:0.0

apt-get install qtcreator

root@ubuntu-mate:~# qtcreator

Can you give me some help information? thanks

Please configure Linux Kernel as the following.

Device Drivers --->
Graphics support --->
<M> IPUv3 core support

and higher DRI support) --->
Arm devices --->
[M] Arm Mali Display Processor
[M] DRM Support for Freescale i.mx
[M] IMX8 HD Display Controller
Common Clock Framework--->
[*] Clock driver for LS1028A Display output

When Linux Kernel booting up, please insert the following Linux Kernel module

# insmod drm_panel_orientation_quirks.ko
# insmod drm.ko
# insmod drm_kms_helper.ko
# insmod imx_hdp_common.ko
# insmod mali-dp.ko
# insmod imx-hdptx.ko

Please refer to "7.2.18 LCD and display transmitter controller" in LSDK 19.09 user guide for details.

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

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
