Cryolitia worked on the linuxdeepin/dde-session-shell repository, focusing on improving the reliability and packaging quality of the Deepin Desktop Environment session shell. During this period, Cryolitia addressed a critical issue where the Deepin Greeter install script failed to run after system build due to missing executable permissions. By modifying the CMake-based build system configuration, Cryolitia switched the installation method from FILES to PROGRAMS, ensuring the script was installed with the correct permissions. This change automated the startup process for the greeter, reduced manual intervention post-build, and enhanced the overall packaging workflow, demonstrating depth in build system and scripting expertise.
