Description liqianwen loongson_group 2025-06-30 15:19:38 UTC 
【问题描述】
安装dde软件包后重启系统，DDE桌面环境启动失败

【内核版本】
6.6.88-4_rc2.an23.loongarch64

【iso下载】
https://build.openanolis.cn/kojifiles/output/nightly/anolis-23-20250609.1/compose/os/loongarch64/iso/

【复现步骤】
1、yum install gdm


【实际结果】
Failed to enable unit: File /etc/systemd/system/display-manager.service already exists and is a symlink to /usr/lib/systemd/system/gdm.service.
警告：%post(lightdm-1.30.0-11.4.an23.loongarch64) 脚本执行失败，退出状态码为 1

Error in POSTIN scriptlet in rpm package lightdm

【期望结果】
安装dde软件包后，桌面环境可正常启动

先通过iso最小安装将系统安装完成，完后直接安装dde，ligthdm会启动失败，导致dde桌面起不来，需要在额外装xorg-x11-drv-fbdev然后才能通过lightdm正常启动dde

建议吧xorg-x11-drv-fbdev加到dde的安装依赖中
