Below are few bugs in OMLX4 alpha 1 tested on thinkpad t430 (i5-3320M/Intel HD4000 graphics).
Impossible to mount pendrive in Dolphin with exFAT file system under live ISO session and under installed OMLX 4 alpha on SSD drive (encrypted installation, exfat packages are installed) which result in error message:
An error occurred while accessing ‘Home’, the system responded: The requested operation has failed: Error mounting /dev/sdc1 at /media/live/FLASH DRIVE: unknown filesystem type ‘exfat’
Impossible to mount encrypted hard drive with XFS file system under installed OMLX 4 alpha on another SSD drive (encrypted installation) in Dolphin.
Under live ISO session is possibble to mount this encrypted hard drive (works without problems) but with error message in Dolphin:
An error occurred while accessing ‘Home’, the system responded: The device is already mounted: Device /dev/dm-0 is already mounted at `/media/live/Volume_label’.
Libre Office doesn’t recognize installed Java Environment.
There is no way to switch to OpenGL and OpenCL in Libre Office (no switch/inactive).
Very small fonts in Libre Office menu.
Firefox sometimes works strange. Doesn’t load the web pages and is impossible to refresh these blank pages. Restarting Firefox is the only solution.
System doesn’t boot after system upgrade with kernel-release-desktop-4.19.12-1omv4000 (with 4.19.8 works well).
Anyway OMLX4 looks promising
